+ * rsvg_handle_render_cairo:
+ * @handle: A #RsvgHandle
+ * @cr: A Cairo context
+ *
+ * Draws a loaded SVG handle to a Cairo context.  Please try to use
+ * rsvg_handle_render_document() instead, which allows you to pick the size
+ * at which the document will be rendered.
+ *
+ * Historically this function has picked a size by itself, based on the following rules:
+ *
+ * <itemizedlist>
+ *   <listitem>
+ *     If the SVG document has both <literal>width</literal> and <literal>height</literal>
+ *     attributes with physical units (px, in, cm, mm, pt, pc) or font-based units (em,
+ *     ex), the function computes the size directly based on the dots-per-inch (DPI) you
+ *     have configured with rsvg_handle_set_dpi().  This is the same approach as
+ *     rsvg_handle_get_intrinsic_size_in_pixels().
+ *   </listitem>
+ *   <listitem>
+ *     Otherwise, if there is a <literal>viewBox</literal> attribute and both
+ *     <literal>width</literal> and <literal>height</literal> are set to
+ *     <literal>100%</literal> (or if they don't exist at all and thus default to 100%),
+ *     the function uses the width and height of the viewBox as a pixel size.  This
+ *     produces a rendered document with the correct aspect ratio.
+ *   </listitem>
+ *   <listitem>
+ *      Otherwise, this function computes the extents of every graphical object in the SVG
+ *      document to find the total extents.  This is moderately expensive, but no more expensive
+ *      than rendering the whole document, for example.
+ *   </listitem>
+ *   <listitem>
+ *     This function cannot deal with percentage-based units for <literal>width</literal>
+ *     and <literal>height</literal> because there is no viewport against which they could
+ *     be resolved; that is why it will compute the extents of objects in that case.  This
+ *     is why we recommend that you use rsvg_handle_render_document() instead, which takes
+ *     in a viewport and follows the sizing policy from the web platform.
+ *   </listitem>
+ * </itemizedlist>
+ *
+ * Drawing will occur with respect to the @cr's current transformation: for example, if
+ * the @cr has a rotated current transformation matrix, the whole SVG will be rotated in
+ * the rendered version.
+ *
+ * This function depends on the #RsvgHandle's DPI to compute dimensions in
+ * pixels, so you should call rsvg_handle_set_dpi() beforehand.
+ *
+ * Note that @cr must be a Cairo context that is not in an error state, that is,
+ * cairo_status() must return #CAIRO_STATUS_SUCCESS for it.  Cairo can set a
+ * context to be in an error state in various situations, for example, if it was
+ * passed an invalid matrix or if it was created for an invalid surface.
+ *
+ * Returns: %TRUE if drawing succeeded; %FALSE otherwise.
+ * Since: 2.14
+ *
+ * Deprecated: 2.52.  Please use rsvg_handle_render_document() instead; that function lets
+ * you pass a viewport and obtain a good error message.

+ * Librsvg provides a few C macros that C and C++ programs can use to
+ * check the version being used at compile-time, that is, the API that
+ * the program expects to have.  This is useful for programs that need
+ * to conditionally compile code with <literal>#ifdef</literal> blocks
+ * depending on the version of librsvg that may be available during
+ * compilation.
+ *
+ * Librsvg also provides a few global constants that can be used to
+ * check the version of librsvg being used at run-time.  This is
+ * useful to know which version of librsvg is actually being used on
+ * the system where the program is running.
+ */
+
+/**
+ * LIBRSVG_MAJOR_VERSION:
+ *
+ * This is a C macro that expands to a number with the major version
+ * of librsvg against which your program is compiled.
+ *
+ * For example, for librsvg-2.3.4, the major version is 2.
+ *
+ * C programs can use this as a compile-time check for the required
+ * version, but note that generally it is a better idea to do
+ * compile-time checks by calling <ulink
+ * url="https://www.freedesktop.org/wiki/Software/pkg-config/">pkg-config</ulink>

+/**
+ * SECTION: rsvg-handle
+ * @short_description: Loads SVG data into memory.
+ *
+ * This is the main entry point into the librsvg library.  An RsvgHandle is an
+ * object that represents SVG data in memory.  Your program creates an
+ * RsvgHandle from an SVG file, or from a memory buffer that contains SVG data,
+ * or in the most general form, from a #GInputStream that will provide SVG data.
+ *
+ * Librsvg can load SVG images and render them to Cairo surfaces,
+ * using a mixture of SVG's [static mode] and [secure static mode].
+ * Librsvg does not do animation nor scripting, and can load
+ * references to external data only in some situations; see below.
+ *
+ * Librsvg supports reading <ulink
+ * url="https://www.w3.org/TR/SVG11/">SVG 1.1</ulink> data, and is
+ * gradually adding support for features in <ulink
+ * url="https://www.w3.org/TR/SVG2/">SVG 2</ulink>.  Librsvg also supports
+ * SVGZ files, which are just an SVG stream compressed with the GZIP algorithm.
+ *
+ * # The "base file" and resolving references to external files
+ *
+ * When you load an SVG, librsvg needs to know the location of the "base file"
+ * for it.  This is so that librsvg can determine the location of referenced
+ * entities.  For example, say you have an SVG in <filename>/foo/bar/foo.svg</filename>
+ * and that it has an image element like this:
+ *
+ * |[
+ * <image href="resources/foo.png" .../>
+ * ]|
+ *
+ * In this case, librsvg needs to know the location of the toplevel
+ * <filename>/foo/bar/foo.svg</filename> so that it can generate the appropriate
+ * reference to <filename>/foo/bar/resources/foo.png</filename>.
+ *
+ * ## Security and locations of referenced files
+ *
+ * When processing an SVG, librsvg will only load referenced files if they are
+ * in the same directory as the base file, or in a subdirectory of it.  That is,
+ * if the base file is <filename>/foo/bar/baz.svg</filename>, then librsvg will
+ * only try to load referenced files (from SVG's
+ * <literal>&lt;image&gt;</literal> element, for example, or from content
+ * included through XML entities) if those files are in <filename>/foo/bar/<!--
+ * -->*</filename> or in <filename>/foo/bar/<!-- -->*<!-- -->/.../<!--
+ * -->*</filename>.  This is so that malicious SVG files cannot include files
+ * that are in a directory above.
+ *
+ * The full set of rules for deciding which URLs may be loaded is as follows;
+ * they are applied in order.  A referenced URL will not be loaded as soon as
+ * one of these rules fails:
+ *
+ * <orderedlist>
+ *   <listitem>
+ *     All <literal>data:</literal> URLs may be loaded.  These are sometimes used
+ *     to include raster image data, encoded as base-64, directly in an SVG file.
+ *   </listitem>
+ *
+ *   <listitem>
+ *     All other URL schemes in references require a base URL.  For
+ *     example, this means that if you load an SVG with
+ *     rsvg_handle_new_from_data() without calling rsvg_handle_set_base_uri(),
+ *     then any referenced files will not be allowed (e.g. raster images to be
+ *     loaded from other files will not work).
+ *   </listitem>
+ *
+ *   <listitem>
+ *     If referenced URLs are absolute, rather than relative, then they must
+ *     have the same scheme as the base URL.  For example, if the base URL has a
+ *     "<literal>file</literal>" scheme, then all URL references inside the SVG must
+ *     also have the "<literal>file</literal>" scheme, or be relative references which
+ *     will be resolved against the base URL.
+ *   </listitem>
+ *
+ *   <listitem>
+ *     If referenced URLs have a "<literal>resource</literal>" scheme, that is,
+ *     if they are included into your binary program with GLib's resource
+ *     mechanism, they are allowed to be loaded (provided that the base URL is
+ *     also a "<literal>resource</literal>", per the previous rule).
+ *   </listitem>
+ *
+ *   <listitem>
+ *     Otherwise, non-<literal>file</literal> schemes are not allowed.  For
+ *     example, librsvg will not load <literal>http</literal> resources, to keep
+ *     malicious SVG data from "phoning home".
+ *   </listitem>
+ *
+ *   <listitem>
+ *     A relative URL must resolve to the same directory as the base URL, or to
+ *     one of its subdirectories.  Librsvg will canonicalize filenames, by
+ *     removing ".." path components and resolving symbolic links, to decide whether
+ *     files meet these conditions.
+ *   </listitem>
+ * </orderedlist>
+ *
+ * # Loading an SVG with GIO
+ *
+ * This is the easiest and most resource-efficient way of loading SVG data into
+ * an #RsvgHandle.
+ *
+ * If you have a #GFile that stands for an SVG file, you can simply call
+ * rsvg_handle_new_from_gfile_sync() to load an RsvgHandle from it.
+ *
+ * Alternatively, if you have a #GInputStream, you can use
+ * rsvg_handle_new_from_stream_sync().
+ *
+ * Both of those methods allow specifying a #GCancellable, so the loading
+ * process can be cancelled from another thread.
+ *
+ * ## Loading an SVG from memory
+ *
+ * If you already have SVG data in a byte buffer in memory, you can create a
+ * memory input stream with g_memory_input_stream_new_from_data() and feed that
+ * to rsvg_handle_new_from_stream_sync().
+ *
+ * Note that in this case, it is important that you specify the base_file for
+ * the in-memory SVG data.  Librsvg uses the base_file to resolve links to
+ * external content, like raster images.
+ *
+ * # Loading an SVG without GIO
+ *
+ * You can load an RsvgHandle from a simple filename or URI with
+ * rsvg_handle_new_from_file().  Note that this is a blocking operation; there
+ * is no way to cancel it if loading a remote URI takes a long time.  Also, note that
+ * this method does not let you specify #RsvgHandleFlags.
+ *
+ * Otherwise, loading an SVG without GIO is not recommended, since librsvg will
+ * need to buffer your entire data internally before actually being able to
+ * parse it.  The deprecated way of doing this is by creating a handle with
+ * rsvg_handle_new() or rsvg_handle_new_with_flags(), and then using
+ * rsvg_handle_write() and rsvg_handle_close() to feed the handle with SVG data.
+ * Still, please try to use the GIO stream functions instead.
+ *
+ * # Resolution of the rendered image (dots per inch, or DPI)
+ *
+ * SVG images can contain dimensions like "<literal>5 cm</literal>" or
+ * "<literal>2 pt</literal>" that must be converted from physical units into
+ * device units.  To do this, librsvg needs to know the actual dots per inch
+ * (DPI) of your target device.  You can call rsvg_handle_set_dpi() or
+ * rsvg_handle_set_dpi_x_y() on an RsvgHandle to set the DPI before rendering
+ * it.
+ *
+ * # Rendering
+ *
+ * The preferred way to render a whole SVG document is to use
+ * rsvg_handle_render_document().  Please see its documentation for
+ * details.
+ *
+ * # API ordering
+ *
+ * Due to the way the librsvg API evolved over time, an #RsvgHandle object is available
+ * for use as soon as it is constructed.  However, not all of its methods can be
+ * called at any time.  For example, an #RsvgHandle just constructed with rsvg_handle_new()
+ * is not loaded yet, and it does not make sense to call rsvg_handle_get_dimensions() on it
+ * just at that point.
+ *
+ * The documentation for the available methods in #RsvgHandle may mention that a particular
+ * method is only callable on a "fully loaded handle".  This means either:
+ *
+ * <itemizedlist>
+ *   <listitem>
+ *     The handle was loaded with rsvg_handle_write() and rsvg_handle_close(), and
+ *     those functions returned no errors.
+ *   </listitem>
+ *   <listitem>
+ *     The handle was loaded with rsvg_handle_read_stream_sync() and that function
+ *     returned no errors.
+ *   </listitem>
+ * </itemizedlist>
+ *
+ * Before librsvg 2.46, the library did not fully verify that a handle was in a
+ * fully loaded state for the methods that require it.  To preserve
+ * compatibility with old code which inadvertently called the API without
+ * checking for errors, or which called some methods outside of the expected
+ * order, librsvg will just emit a g_critical() message in those cases.
+ *
+ * New methods introduced in librsvg 2.46 and later will check for the correct
+ * ordering, and panic if they are called out of order.  This will abort
+ * the program as if it had a failed assertion.
