| | '''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. |
| | |
