// Draws GL content onto a cairo context.
//
// 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 @surface 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 surface 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.
