It takes a render buffer ID (/@sourceType@/ == @/GL_RENDERBUFFER/@) or a texture id (/@sourceType@/ == @/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.
