| '''OpenGL extension SGI.make_current_read |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GLX.SGI.make_current_read to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| The association of the current context with a drawable is extended to allow |
| separate write and read drawables. This paves the way for allowing |
| preprocessing of image data in an "off screen" window which is then read |
| into the visible window for final display. Similarly it sets the |
| frame-work for direct transfer of video to the GL, by treating the video |
| as a special kind of read drawable (a.k.a, readable). |
