| '''OpenGL extension SUNX.constant_data |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.SUNX.constant_data to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension allows the pixel data specified by the |
| application to be used internally without making a second copy. |
| This extension affects how the pixel data in client memory is |
| interpreted and therefore affects DrawPixels, Bitmap, |
| PolygonStipple, TexImage1D, TexImage2D, TexImage3DEXT, |
| ColorTableSGI. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/SUNX/constant_data.txt |
