- * GdkGLFlags:

- * @GDK_GL_ALWAYS: Make all newly created windows use GL rendering
- * @GDK_GL_SOFTWARE_DRAW_GL: Always use software fallback for drawing
- *     GL content to a cairo_t. This disables the fast paths that exist for
- *     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
- *
- * Flags that influence the OpenGL rendering used by GDK.
