| '''OpenGL extension EXT.visual_info |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GLX.EXT.visual_info to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension allows the user to request a particular X visual |
| type to be associated with a GLX visual, and allows the user |
| to query the X visual type underlying a GLX visual. |
| |
| In addition, this extension provides a means to request a visual |
| with a transparent pixel and to query whether a visual supports a |
| transparent pixel value and the value of the transparent pixel. |
| Note that the notion of level and transparent pixels are orthogonal as |
| both layer 1 and layer 0 visuals may or may not have a transparent pixel |
| value. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/EXT/visual_info.txt |
