+.SH NAME
+DBE - Double Buffer Extension
+.SH SYNOPSIS
+The Double Buffer Extension (DBE) provides a standard way to utilize
+double-buffering within the framework of the X Window System.
+Double-buffering uses two buffers, called front and back, which hold images.
+The front buffer is visible to the user; the back buffer is not.  Successive
+frames of an animation are rendered into the back buffer while the previously
+rendered frame is displayed in the front buffer.  When a new frame is ready,
+the back and front buffers swap roles, making the new frame visible.  Ideally, 
+this exchange appears to happen instantaneously to the user, with no visual
+artifacts.  Thus, only completely rendered images are presented to the user, 
+and remain visible during the entire time it takes to render a new frame.  The
+result is a flicker-free animation.
+.SH DESCRIPTION
+.B Concepts
+.RS
+Normal windows are created using
+.B XCreateWindow()
+or
+.B XCreateSimpleWindow(),
+which allocate a set of window attributes and, for InputOutput windows, a front
+buffer, into which an image can be drawn.  The contents of this buffer will be 
+displayed when the window is visible.
+
+This extension enables applications to use double-buffering with a window.
+This involves creating a second buffer, called a back buffer, and associating
+one or more back buffer names
+.I (XIDs)
+with the window, for use when referring 
+to (i.e., drawing to or reading from) the window's back buffer.
+The back buffer name is a drawable of type
+.I XdbeBackBuffer.
+
+DBE provides a relative double-buffering model.  One XID, the window,
+always refers to the front buffer.  One or more other XIDs, the back buffer
+names, always refer to the back buffer.  After a buffer swap, the window 
+continues to refer to the (new) front buffer, and the back buffer name
+continues to refer to the (new) back buffer.  Thus, applications and toolkits
+that want to just render to the back buffer always use the back buffer name
+for all drawing requests to the window.  Portions of an application that want
+to render to the front buffer always use the window XID for all drawing 
+requests to the window.
+
+Multiple clients and toolkits can all use double-buffering on the same window.
+DBE does not provide a request for querying whether a window has 
+double-buffering support, and if so, what the back buffer name is.  Given the 
+asynchronous nature of the X Window System, this would cause race
+conditions.  Instead, DBE allows multiple back buffer names to exist for the 
+same window; they all refer to the same physical back buffer.  The first time a 
+back buffer name is allocated for a window, the window becomes
+double-buffered and the back buffer name is associated with the window.
+Subsequently, the window already is a double-buffered window, and nothing
+about the window changes when a new back buffer name is allocated, except
+that the new back buffer name is associated with the window.  The window
+remains double-buffered until either the window is destroyed, or until all of
+the back buffer names for the window are deallocated.
+
+In general, both the front and back buffers ae treated the same.  In 
+particular, here are some important characteristics:
+
+.RS
+Only one buffer per window can be visible at a time (the front buffer).
+
+Both buffers associated with a window have the same visual type, depth,
+width, height, and shape as the window.
+
+Both buffers associated with a window are "visible" (or "obscured") in
+the same way.  When an Expose event is generated for a window, this 
+event is considered to apply to both buffers equally.  When a 
+double-buffered window is exposed, both buffers are tiled with the 
+window background.
+Even though the back buffer is not visible, terms such as obscure apply to the 
+back buffer as well as to the front buffer.
+
+It is acceptable at any time to pass an
+.I XdbeBackBuffer
+in any function that expects a drawable.
+This enables an application to draw directly into
+.I XdbeBackBuffer
+in the same fashion as it would draw into any other drawable.
+
+It is an error (Window) to pass an
+.I XdbeBackBuffer
+in a function that expects a Window.
+
+An
+.I XdbeBackBuffer
+will never be sent in a reply, event, or error where a Window is specified.
+
+If backing-store and save-under applies to a double-buffered
+window, it applies to both buffers equally.
+
+If the
+.B XClearArea()
+or
+.B XClearWindow()
+function is executed on a
+double-buffered window, the same area in both the front and back buffers
+is cleared.
+.RE
+
+The effect of passing a window to a function that accepts a drawable
+is unchanged by this extension.  The window and front buffer are synonomous
+with each other.  This includes obeying the
+.B XGetImage()
+and
+.B XGetSubImage()
+semantics and the subwindow-mode semantics if a graphics context is
+involved.  Regardless of whether the window was explicitly passed in an
+.B XGetImage()
+or
+.B XGetSubImage()
+call, or implicitly referenced (i.e., one of
+the window's ancestors was passed in the function), the front (i.e. visible)
+buffer is always referenced.
+Thus, DBE-naive screen dump clients will always get the front buffer.
+.B XGetImage()
+and
+.B XGetSubImage()
+on a back
+buffer return undefined image contents for any obscured regions of the back
+buffer that fall within the image.
+
+Drawing to a back buffer always uses the clip region that would be used to 
+draw to the front buffer with a GC subwindow-mode of ClipByChildren.  If an 
+ancestor of a double-buffered window is drawn to with a GC having a
+subwindow-mode of IncludeInferiors, the effect on the double-buffered
+window's back buffer depends on the depth of the double-buffered window
+and the ancestor.  If the depths are the same, the contents of the back buffer
+of the double-buffered window are not changed.  If the depths are different,
+the contents of the back buffer of the double-buffered window are undefined 
+for the pixels that the IncludeInferiors drawing touched.
+
+DBE adds no new events.  DBE does not extend the semantics of any existing
+events with the exception of adding a new drawable type called
+.I XdbeBackBuffer.
+
+If events, replies, or errors that contain a drawable
+(e.g., GraphicsExpose) are generated in response to a request, the
+drawable returned will be the one specified in the request.
+
+DBE advertises which visuals support double buffering.
+
+DBE does not include any timing or synchronization facilities.  Applications
+that need such facilities (e.g., to maintain a constant frame rate) should
+investigate the Synchronization Extension, an X Consortium standard.
+.RE
+
+.B Window Management Operations
+
+.RS
+The basic philosophy of DBE is that both buffers are treated the same by
+X window management operations.
+
+When a double-buffered window is destroyed,
+both buffers associated with the window are destroyed, and all back buffer
+names associated with the window are freed.
+
+If the size of a double-buffered window changes, both 
+buffers assume the new size.  If the window's size increases, the effect on the 
+buffers depends on whether the implementation honors bit gravity for buffers.
+If bit gravity is implemented, then the contents of both buffers are moved in 
+accordance with the window's bit gravity,
+and the remaining areas are tiled with the window background.  If 
+bit gravity is not implemented, then the entire unobscured region of both 
+buffers is tiled with the window background.  In either case, Expose events are
+generated for the region that is tiled with the window background.
+
+If the
+.B XGetGeometry()
+function is executed on an
+.I XdbeBackBuffer,
+the returned x, y, and border-width will be zero.
+
+If the Shape extension
+.B ShapeRectangles, ShapeMask, ShapeCombine,
+or
+.B ShapeOffset
+request is executed on a double-buffered window, both 
+buffers are reshaped to match the new window shape.  The region difference
+D = new shape - old shape is tiled with the window background in both 
+buffers, and Expose events are generated for D.
+.RE
+
+.B Complex Swap Actions
+
+.RS
+DBE has no explicit knowledge of ancillary buffers (e.g. depth buffers or 
+alpha buffers), and only has a limited set of defined swap actions.  Some
+applications may need a richer set of swap actions than DBE provides.  Some 
+DBE implementations have knowledge of ancillary buffers, and/or can provide 
+a rich set of swap actions. Instead of continually extending DBE to increase
+its set of swap actions, DBE provides a flexible "idiom" mechanism.  If an 
+applications's needs are served by the defined swap actions, it should use
+them; otherwise, it should use the following method of expressing a complex
+swap action as an idiom.  Following this policy will ensure the best possible
+performance across a wide variety of implementations.
+
+As suggested by the term "idiom," a complex swap action should be expressed 
+as a group/series of requests.  Taken together, this group of requests may be 
+combined into an atomic operation by the implementation, in order to 
+maximize performance.  The set of idioms actually recognized for optimization
+is implementation dependent.  To help with idiom expression and 
+interpretation, an idiom must be surrounded by two function calls:  
+.B XdbeBeginIdiom()
+and
+.B XdbeEndIdiom().
+Unless this begin-end pair
+surrounds the idiom, it may not be recognized by a given implementation, and 
+performance will suffer.
+
+For example, if an application wants to swap buffers for two windows, and use
+X to clear only certain planes of the back buffers, the application would
+make the following calls as a group, and in the following order:
+
+.RS
+.B XdbeBeginIdiom().
+
+.B XdbeSwapBuffers()
+with XIDs for two windows, each of which uses a swap action of Untouched.
+
+.B XFillRectangle()
+to the back buffer of one window.
+
+.B XFillRectangle()
+to the back buffer of the other window.
+
+.B XdbeEndIdiom().
+.RE
+
+The
+.B XdbeBeginIdiom()
+and
+.B XdbeEndIdiom()
+functions do not perform any
+actions themselves.  They are treated as markers by implementations that can 
+combine certain groups/series of requests as idioms, and are ignored by other
+implementations or for non-recognized groups/series of requests.  If these
+function calls are made out of order, or are mismatched, no errors are sent,
+and the functions are executed as usual, though performance may suffer.
+
+.B XdbeSwapBuffers()
+need not be included in an idiom.  For
+example, if a swap action of Copied is desired, but only some of the planes
+should be copied,
+.B XCopyArea()
+may be used instead of 
+.B XdbeSwapBuffers().
+If
+.B XdbeSwapBuffers()
+is included in an idiom, it should immediately follow the
+.B XdbeBeginIdiom()
+call.  Also, when the 
+.B XdbeSwapBuffers()
+is included in an idiom, that request's swap action will 
+still be valid, and if the swap action might overlap with another request, then 
+the final result of the idiom must be as if the separate requests were executed
+serially.  For example, if the specified swap action is Untouched, and if a 
+.B XFillRectangle()
+using a client clip rectangle is done to the window's back
+buffer after the
+.B XdbeSwapBuffers()
+call, then the contents of the new 
+back buffer (after the idiom) will be the same as if the idiom was not
+recognized by the implementation.
+
+It is highly recommended that API providers define, and application 
+developers use, "convenience" functions that allow client applications to call
+one procedure that encapsulates common idioms.  These functions will
+generate the
+.B XdbeBeginIdiom(),
+idiom, and 
+.B XdbeEndIdiom()
+calls.  Usage of these functions will ensure best possible
+performance across a wide variety of implementations.

+    Display  *dpy,
+    Drawable *screen_specifiers,
+    int      *num_screens)
+.SH DESCRIPTION
+This function returns information about which visuals support double
+buffering.  The argument
+.I num_screens
+specifies how many elements there are 
+in the
+.I screen_specifiers
+list.  Each drawable in
+.I screen_specifiers
+designates a 
+screen for which the supported visuals are being requested.  If
+.I num_screens
+is zero, information for all screens is requested.  In this case, upon return
+from this function,
+.I num_screens
+will be set to the number of screens that were
+found.  If an error occurs, this function returns NULL, else it returns a
+pointer to a list of
+.I XdbeScreenVisualInfo
+structures of length
+.I num_screens.
+The nth
+element in the returned list corresponds to the nth drawable in the 
+.I screen_specifiers
+list, unless
+.I num_screens
+was passed in with the value zero,
+in which case the nth element in the returned list corresponds to the nth screen
+of the server, starting with screen zero.  The
+.I XdbeScreenVisualInfo
+structure has the following fields:
+
+     int            count
+     XdbeVisualInfo *visinfo
+
+.I count
+specifies the number of items in
+.I visinfo.
+.I visinfo
+specifies a list of visuals, depths, and performance hints for this screen.
+
+The
+.I XdbeVisualInfo
+structure has the following fields:
+
+     VisualID visual
+     int      depth
+     int      perflevel
+
+.I visual
+specifies one visual ID that supports double-buffering.
+.I depth
+specifies the depth of the visual.
+.I perflevel
+is a performance hint.
+
+The only operation defined on a
+.I perflevel
+is comparison to a
+.I perflevel
+of another visual on the same screen.  The visual having the higher
+.I perflevel
+is likely to have better double-buffering graphics performance than the visual
+having the lower
+.I perflevel.
+Nothing can be deduced from the following: the magnitude of the difference
+of two
+.I perflevels,
+a
+.I perflevel
+value in isolation, or comparing
+.I perflevels
+from different servers.

+This function swaps the front and back buffers for a list of windows.  The
+argument
+.I num_windows
+specifies how many windows are to have their buffers

+
+.I swap_window
+specifies the window for which to swap buffers.
+.I swap_action
+specifies the swap action to use for this
+.I swap_window.
+
+.I swap_action
+determines what will happen to the new back buffer of the
+.I swap_window
+it is paired with in the list in addition to making the old back buffer
+become visible.  The defined actions are as follows:
+
+.IP XdbeUndefined
+The contents of the new back buffer become undefined.  This may be the most
+efficient action since it allows the implementation to discard the contents of
+the buffer if it needs to.
+.IP XdbeBackground
+The unobscured region of the new back buffer will be tiled with the
+window background.  The background action allows devices to use a fast clear
+capability during a swap.
+.IP XdbeUntouched
+The unobscured region of the new back buffer will be unmodified by the swap.
+.IP XdbeCopied
+The unobscured region of the new back buffer will be the contents of the old
+back buffer
+.SH ERRORS
+.IP BadMatch
+A non-double-buffered window was specififed or a window was specified twice.
+.IP BadWindow
+An invalid window was specified.
+.IP BadValue

+.SH NAME
+XeviQueryExtension, XeviQueryVersion, XeviGetVisualInfo - X Extended Visual Information functions
+.SH SYNOPSIS
+#include <X11/extensions/XEVI.h>
+
+Bool
+XeviQueryExtension (Display *dpy);
+.LP
+Bool
+XeviQueryVersion (Display *dpy, 
+    int *major_version_return,

+    int n_visual, ExtendedVisualInfo ** evi_return,
+    int * n_info_return);
+.fi
+.SH DESCRIPTION
+The
+X11 Extended Visual Information extension (EVI) allows a client to determine
+information about core X visuals beyond what the core protocol provides.
+
+The EVI application programming library contains the interfaces described below.
+With the exception of
+.BR XeviQueryExtension,
+if any of these routines are
+called with a display that does not support the extension, the
+ExtensionErrorHandler (which can be set with
+.BR XSetExtensionErrorHandler
+and functions the same way as
+.BR XSetErrorHandler )
+will be called and the function will then return.
+.PP
+.BR XeviQueryExtension
+returns 
+.BR True
+if the Extended Visual Information extension is available on the given display.
+A client must call
+.BR XeviQueryExtension
+before calling any other EVI
+function in order to negotiate a compatible protocol version; otherwise
+the client will get undefined behavior (EVI may or may not work).
+.PP
+.BR XeviQueryVersion
+returns
+.BR True
+if the request succeeded; the values of the major and minor protocol
+version supported by the server are returned in
+.I major_version_return
+and
+.I minor_version_return.
+.PP
+.BR XeviGetVisualInfo
+returns a list of ExtendedVisualInfo structures that describe
+visual information beyond that supported by the core protocol. This includes 
+layer information relevant for systems supporting overlays and/or underlay
+planes, and information that allows applications better to determine the level
+of hardware support for multiple colormaps. XeviGetVisualInfo returns 
+.BR Success 
+if successful, or an X error otherwise.
+If the argument
+.I visual
+is NULL, then information for all visuals of all 
+screens is returned. Otherwise, it's a pointer to a list of visuals for which
+extended visual information is desired.
+.I n_visual
+is the number of elements in the array visual.
+.I evi_return
+returns a pointer to a list of ExtendedVisualInfo. When done, the client
+should free the list using XFree\.
+.I n_info_return
+returns the number of elements in the array evi_return.
+.LP
+The
+.BR ExtendedVisualInfo
+structure has the following fields:
+.in +.5i
+.nf
+.ta 1.6i
+VisualID	\fIcore_visual_id\fR    
+int 	\fIscreen\fR	    	
+int 	\fIlevel\fR 	    	
+unsigned int	\fItransparency_type\fR 
+unsigned int	\fItransparency_value\fR 
+unsigned int	\fImin_hw_colormaps\fR
+unsigned int	\fImax_hw_colormaps\fR
+unsigned int	\fInum_colormap_conflicts\fR
+VisualID *  	\fIcolormap_conflicts\fR
+.fi
+.LP
+The combination of 
+.I core_visual_id
+and
+.I screen
+number uniquely specify the visual being described.
+.LP
+.I level
+returns the level number for the visual, 0 for normal planes, > 0 for
+overlays, < 0 for underlays.
+.LP
+.I
+transparency_type
+returns the type of transparency supported by the visual. XEVI_TRANSPARENCY_NONE if
+there are no transparent pixels, XEVI_TRANSPARENCY_PIXEL if the visual supports
+a transparent pixel, XEVI_TRANSPARENCY_MASK if the visual supports transparent
+plane(s).
+.LP
+.I transparency_value
+returns the pixel/plane value to set for transparency if transparency_type isn't
+XEVI_TRANSPARENCY_NONE.
+.LP
+.I min_hw_colormaps
+and
+.I max_hw_colormaps
+return the minimum and maximum number of hardware colormaps backing up the
+visual. 
+.LP
+.I num_colormap_conflicts
+returns the number of elements in 
+.I colormap_conflicts.
+This array returns a list of visuals that may cause conflicts in the use of the
+hardware colormap. For example, if a 12-bit hardware colormap is overloaded to
+support 8-bit colormaps, the corresponding 8-bit visuals would conflict with the
+12-bit visuals.
+
+.SH ERRORS
+.BR XeviGetVisualInfo
+will return
+.I BadValue

+.SH DESCRIPTION
+The application programming library for the
+\fIX11 Double-Buffering, Multi-Buffering, and Stereo Extension\fP
+contains the interfaces described below.
+With the exception of
+.ZN XmbufQueryExtension ,
+if any of these routines are
+called with a display that does not support the extension, the
+ExtensionErrorHandler (which can be set with
+.ZN XSetExtensionErrorHandler
+and functions the same way as
+.ZN XSetErrorHandler )
+will be called and the function will then return.
+.PP
+.ZN XmbufQueryExtension
+returns 
+.ZN True
+if the multibuffering/stereo 
+extension is available on the
+given display.  If the extension exists, the value of the first event
+code (which should be added to the event type constants
+.ZN MultibufferClobberNotify
+and 
+.ZN MultibufferUpdateNotify
+to get the actual
+values) is stored into event_base_return and the value of the first
+error code (which should be added to the error type constant
+.ZN MultibufferBadBuffer
+to get the actual value) is stored into error_base_return.
+.PP
+.ZN XmbufGetVersion
+gets the major and minor version numbers of the extension.  
+The return
+value is zero if an error occurs or non-zero if no error happens.
+.PP
+.ZN XmbufCreateBuffers
+requests that "count" buffers be 
+created with the given update_action
+and update_hint and be associated with the indicated window.  The
+number of buffers created is returned (zero if an error occurred)
+and buffers_update is filled in with that many Multibuffer identifiers.
+.PP
+.ZN XmbufDestroyBuffers
+destroys the buffers associated 
+with the given window.
+.PP
+.ZN XmbufDisplayBuffers
+displays the indicated buffers their
+appropriate windows within
+max_delay milliseconds after min_delay milliseconds have passed.
+No two buffers may be associated with the same window or else a Matc
+error is generated.
+.PP
+.ZN XmbufGetWindowAttributes
+gets the multibuffering attributes that apply 
+to all buffers associated
+with the given window.
+The list of buffers returns may be freed with 
+.ZN XFree .
+Returns non-zero on success and zero if an error occurs.
+.PP
+.ZN XmbufChangeWindowAttributes
+sets the multibuffering attributes 
+that apply to all buffers associated
+with the given window.  This is currently limited to the update_hint.
+.PP
+.ZN XmbufGetBufferAttributes
+gets the attributes for the indicated buffer.
+Returns non-zero on
+success and zero if an error occurs.
+.PP
+.ZN XmbufChangeBufferAttributes
+sets the attributes for the indicated buffer.
+This is currently limited to the event_mask.
+.PP
+.ZN XmbufGetScreenInfo
+gets the parameters controlling how
+mono and stereo windows may be
+created on the screen of the given drawable.  The numbers of sets of
+visual and depths are returned in nmono_return and nstereo_return.  If
+nmono_return is greater than zero, then mono_info_return is set to the
+address of an array of 
+.ZN XmbufBufferInfo
+structures describing the
+various visuals and depths that may be used.  Otherwise,
+mono_info_return is set to NULL.  Similarly, stereo_info_return is set
+according to nstereo_return.  The storage returned in mono_info_return
+and stereo_info_return may be released by 
+.ZN XFree .
+If no errors are
+encounted, non-zero will be returned.
+.PP
+.ZN XmbufCreateStereoWindow
+creates a stereo window in the same way that 
+.ZN XCreateWindow
+creates a mono window.  The buffer ids for the left and right buffers are
+returned in left_return and right_return, respectively.  If an
+extension error handler that returns is installed, 
+.ZN None
+will be returned if the extension is not available on this display.
