| | '''OpenGL extension MESA.copy_sub_buffer |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GLX.MESA.copy_sub_buffer to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | The glxCopySubBufferMESA() function copies a rectangular region |
| | of the back color buffer to the front color buffer. This can be |
| | used to quickly repaint 3D windows in response to expose events |
| | when the back color buffer cannot be damaged by other windows. |
| | |
| | The official definition of this extension is available here: |
| | http://www.opengl.org/registry/specs/MESA/copy_sub_buffer.txt |
