OpenGL.GL.IBM.rasterpos_clip

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
