| '''OpenGL extension EXT.visual_rating |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GLX.EXT.visual_rating to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension allows servers to identify a particular GLX visual as |
| undesirable. A new visual attribute is introduced, providing a way |
| for servers to specify caveats (e.g., slow) for a visual. The attribute |
| may be queried using glXGetConfig, and can therefore be used by |
| application-specific visual selection routines. The new attribute is |
| also used by glXChooseVisual to discriminate against visuals with |
| caveats. |
| |
| This extension allows servers to export visuals with improved features |
| or image quality, but lower performance or greater system burden, |
| without having to have these visuals selected preferentially. It is |
| intended to insure that most applications get the "right" visual, not |
| that all applications do. |
| |
