* Don't build cogl-gles2-gears if configured with --disable-cogl-gles2Neil Roberts2012-08-061-1/+4
| | | | | | | | | | | The cogl-gles2-gears example will fail to build unless --enable-cogl-gles2 is enabled in the configure script because it depends on libcogl-gles2. This patch makes it only conditionally build the example depending on the BUILD_COGL_GLES2 automake conditional.

* Adds gles2-context renderer constraintRobert Bragg2012-08-062-4/+16
| | | | | | | | | | | | | | This adds a new renderer constraint enum: COGL_RENDERER_CONSTRAINT_SUPPORTS_GLES2_CONTEXT that can be used by applications to ensure the renderer they connect to has support for creating a GLES2 context via cogl_gles2_context_new(). The cogl-gles2-context and cogl-gles2-gears examples and the conformance tests have been updated to use this constraint.

* Adds initial GLES2 integration supportRobert Bragg2012-08-063-1/+153
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes it possible to integrate existing GLES2 code with applications using Cogl as the rendering api. Currently all GLES2 usage is handled with separate GLES2 contexts to ensure that GLES2 api usage doesn't interfere with Cogl's own use of OpenGL[ES]. The api has been designed though so we can provide tighter integration later. The api would allow us to support GLES2 virtualized on top of an OpenGL/GLX driver as well as GLES2 virtualized on the core rendering api of Cogl itself. Virtualizing the GLES2 support on Cogl will allow us to take advantage of Cogl debugging facilities as well as let us optimize the cost of allocating multiple GLES2 contexts and switching between them which can both be very expensive with many drivers. As as a side effect of this patch Cogl can also now be used as a portable window system binding API for GLES2 as an alternative to EGL. Parts of this patch are based on work done by Tomeu Vizoso <tomeu.vizoso@collabora.com> who did the first iteration of adding GLES2 API support to Cogl so that WebGL support could be added to webkit-clutter. This patch adds a very minimal cogl-gles2-context example that shows how to create a gles2 context, clear the screen to a random color and also draw a triangle with the cogl api.

* Switch use of primitive glib types to c99 equivalentsRobert Bragg2012-08-067-43/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

* Removes all remaining use of CoglHandleRobert Bragg2012-08-061-2/+2
| | | | | | | | | | | | | | | | | | | Removing CoglHandle has been an on going goal for quite a long time now and finally this patch removes the last remaining uses of the CoglHandle type and the cogl_handle_ apis. Since the big remaining users of CoglHandle were the cogl_program_ and cogl_shader_ apis which have replaced with the CoglSnippets api this patch removes both of these apis. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 6ed3aaf4be21d605a1ed3176b3ea825933f85cf0) Since the original patch was done after removing deprecated API this back ported patch doesn't affect deprecated API and so actually this cherry-pick doesn't remove all remaining use of CoglHandle as it did for the master branch of Cogl.

* Create standalone public wayland client/server headersRobert Bragg2012-03-201-0/+1
| | | | | | | | | | | Because the wayland-client-protocol.h header defines symbols that collide with the wayland-server-protocol.h header we allow applications to explicitly ensure that they are only including one at a time by exposing corresponding <cogl/cogl-wayland-client.h> and <cogl/cogl-wayland-server.h> headers.

* Add -Wmissing-declarations to maintainer flags and fix problemsNeil Roberts2012-03-061-1/+1

This should catch cases were we've defined a function but forgot to put it in a header. In that case it is either only used within one file so we should make it static or we should declare it in a header. The following changes where made to fix problems: • Some functions were made static • cogl-path.h (the one containing the 1.0 API) was split into two files, one defining the functions and one defining the enums so that cogl-path.c can include the enum and function declarations from the 2.0 API as well as the function declarations from the 1.0 API. • cogl2-clip-state has been removed. This only had one experimental function called cogl_clip_push_from_path but as this is unstable we might as well remove it favour of the equivalent cogl_framebuffer_* API. • The GLX, SDL and WGL winsys's now have a private header to define their get_vtable function instead of directly declaring in the C file where it is called. • All places that were calling COGL_OBJECT_DEFINE need to have the cogl_is_whatever function declared so these have been added either as a public function or in a private header. • Some files that were not including the header containing their function declarations have been fixed to do so. • Any unused error quark functions have been removed. If we later want them we should add them back one by one and add a declaration for them in a header. • _cogl_is_framebuffer has been renamed to cogl_is_framebuffer and made a public function with a declaration in cogl-framebuffer.h • Similarly for CoglOnscreen. • cogl_vdraw_indexed_attributes is called cogl_framebuffer_vdraw_indexed_attributes in the header. The definition has been changed to match the header. • cogl_index_buffer_allocate has been removed. This had no declaration and I'm not sure what it's supposed to do. • CoglJournal has been changed to use the internal CoglObject macro so that it won't define an exported cogl_is_journal symbol. • The _cogl_blah_pointer_from_handle functions have been removed. CoglHandle isn't used much anymore anyway and in the few places where it is used I think it's safe to just use the implicit cast from void* to the right type. • The test-utils.h header for the conformance tests explicitly disables the -Wmissing-declaration option using a pragma because all of the tests declare their main function without a header. Any mistakes relating to missing declarations aren't really important for the tests. • cogl_quaternion_init_from_quaternion and init_from_matrix have been given declarations in cogl-quaternion.h Reviewed-by: Robert Bragg <robert@linux.intel.com>

* framebuffer: Add cogl_framebuffer draw methodsRobert Bragg2012-02-096-27/+18
| | | | | | | | | | | | | | | | | | | | | This adds cogl_framebuffer_ apis for drawing attributes and primitives that replace corresponding apis that depend on the default CoglContext. This is part of the on going effort to adapt the Cogl api so it no longer depends on a global context variable. All the new drawing functions also take an explicit pipeline argument since we are also aiming to avoid being a stateful api like Cairo and OpenGL. Being stateless makes it easier for orthogonal components to share access to the GPU. Being stateless should also minimize any impedance miss-match for those wanting to build higher level stateless apis on top of Cogl. Note: none of the legacy, global state options such as cogl_set_depth_test_enabled(), cogl_set_backface_culling_enabled() or cogl_program_use() are supported by these new drawing apis and if set will simply be silently ignored.

| | | | | | | | | | | | | | | It used to be that cogl_framebuffer_allocate() had to be done explicitly but we have since made Cogl lazily allocate framebuffers when they are first used if they haven't already been explicitly allocated. Developers only need to explicitly allocate framebuffers if they are planning to gracefully handle any errors. In cases where the program will simply abort due to an allocation error they can simply rely on implicit allocation which will cause an abort on error.

Most of the examples now just call cogl_poll_get_info and then g_poll with a zero timeout so that they can continue to constantly redraw. The SDL example is a bit special because SDL makes it very difficult to wait on either a timeout or any file descriptors. The SDL winsys is documented not to require blocking on any file descriptors so we can ignore that. It implements the timeout by adding an SDL timer which pushes an event to the queue to wake up SDL_GetEvent. The Cogland example was already using the glib main loop so that one has been updated to add the CoglGLibSource to it. Reviewed-by: Robert Bragg <robert@linux.intel.com>

* Add a strong CoglTexture type to replace CoglHandleRobert Bragg2011-09-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of the on going, incremental effort to purge the non type safe CoglHandle type from the Cogl API this patch tackles most of the CoglHandle uses relating to textures. We'd postponed making this change for quite a while because we wanted to have a clearer understanding of how we wanted to evolve the texture APIs towards Cogl 2.0 before exposing type safety here which would be difficult to change later since it would imply breaking APIs. The basic idea that we are steering towards now is that CoglTexture can be considered to be the most primitive interface we have for any object representing a texture. The texture interface would provide roughly these methods: cogl_texture_get_width cogl_texture_get_height cogl_texture_can_repeat cogl_texture_can_mipmap cogl_texture_generate_mipmap; cogl_texture_get_format cogl_texture_set_region cogl_texture_get_region Besides the texture interface we will then start to expose types corresponding to specific texture types: CoglTexture2D, CoglTexture3D, CoglTexture2DSliced, CoglSubTexture, CoglAtlasTexture and CoglTexturePixmapX11. We will then also expose an interface for the high-level texture types we have (such as CoglTexture2DSlice, CoglSubTexture and CoglAtlasTexture) called CoglMetaTexture. CoglMetaTexture is an additional interface that lets you iterate a virtual region of a meta texture and get mappings of primitive textures to sub-regions of that virtual region. Internally we already have this kind of abstraction for dealing with sliced texture, sub-textures and atlas textures in a consistent way, so this will just make that abstraction public. The aim here is to clarify that there is a difference between primitive textures (CoglTexture2D/3D) and some of the other high-level textures, and also enable developers to implement primitives that can support meta textures since they can only be used with the cogl_rectangle API currently. The thing that's not so clean-cut with this are the texture constructors we have currently; such as cogl_texture_new_from_file which no longer make sense when CoglTexture is considered to be an interface. These will basically just become convenient factory functions and it's just a bit unusual that they are within the cogl_texture namespace. It's worth noting here that all the texture type APIs will also have their own type specific constructors so these functions will only be used for the convenience of being able to create a texture without really wanting to know the details of what type of texture you need. Longer term for 2.0 we may come up with replacement names for these factory functions or the other thing we are considering is designing some asynchronous factory functions instead since it's so often detrimental to application performance to be blocked waiting for a texture to be uploaded to the GPU.
