| '''OpenGL extension IBM.rasterpos_clip |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.IBM.rasterpos_clip to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| IBM_rasterpos_clip extends the semantics of the RasterPos functions. It |
| provides an enable that allows a raster position that would normally be |
| clipped to be treated as a valid (albeit out-of-viewport) position. |
| |
| This extension allows applications to specify geometry-aligned pixel |
| primitives that may be partially off-screen. These primitives are |
| tested on a pixel-by-pixel basis without being rejected completely |
| because of an invalid raster position. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/IBM/rasterpos_clip.txt |
