* drawing directly to a window and instead reads back the pixels into
* a cairo image surface.
* @GDK_GL_SOFTWARE_DRAW_SURFACE: Always use software fallback for
* drawing cairo surfaces onto a GL-using window. This disables e.g.
* texture-from-pixmap on X11.
* @GDK_GL_TEXTURE_RECTANGLE: Use the GL_ARB_texture_rectangle extension
*
