/**
* cairo_surface_create_for_rectangle:
* @target: an existing surface for which the sub-surface will point to
* @x: the x-origin of the sub-surface from the top-left of the target surface (in device-space units)
* @y: the y-origin of the sub-surface from the top-left of the target surface (in device-space units)
* @width: width of the sub-surface (in device-space units)
* @height: height of the sub-surface (in device-space units)
*
* Create a new surface that is a rectangle within the target surface.
* All operations drawn to this surface are then clipped and translated
* onto the target surface. Nothing drawn via this sub-surface outside of
* its bounds is drawn onto the target surface, making this a useful method
* for passing constrained child surfaces to library routines that draw
* directly onto the parent surface, i.e. with no further backend allocations,
* double buffering or copies.
*
* <note><para>The semantics of subsurfaces have not been finalized yet
* unless the rectangle is in full device units, is contained within
* the extents of the target surface, and the target or subsurface's
* device transforms are not changed.</para></note>
*
* Return value: a pointer to the newly allocated surface. The caller
* owns the surface and should call cairo_surface_destroy() when done
* with it.
*
* This function always returns a valid pointer, but it will return a
* pointer to a "nil" surface if @other is already in an error state
* or any other error occurs.
*
* Since: 1.10

*
* This is the main way to draw GL content in GTK+. It takes a render buffer ID
* (@source_type == #GL_RENDERBUFFER) or a texture id (@source_type == #GL_TEXTURE)
* and draws it onto @cr with an OVER operation, respecting the current clip.
* The top left corner of the rectangle specified by @x, @y, @width and @height
* will be drawn at the current (0,0) position of the cairo_t.
*
* This will work for *all* cairo_t, as long as @window is realized, but the
* fallback implementation that reads back the pixels from the buffer may be
* used in the general case. In the case of direct drawing to a window with
* no special effects applied to @cr it will however use a more efficient
* approach.
*
* For #GL_RENDERBUFFER the code will always fall back to software for buffers
* with alpha components, so make sure you use #GL_TEXTURE if using alpha.
*
* Calling this may change the current GL context.
