OpenGL extension NV.multisample_filter_hint
This module customises the behaviour of the OpenGL.raw.GL.NV.multisample_filter_hint to provide a more Python-friendly API
Overview (from the spec)
OpenGL multisampling typically assumes that the samples of a given pixel are weighted uniformly and averaged to compute the pixel's resolved color. This extension provides a hint that permits implementations to provide an alternative method of resolving the color of multisampled pixels.
As an example of such an alternative method, NVIDIA's GeForce3 GPU provides a technique known as Quincunx filtering. This technique is used in two-sample multisampling, but it blends the pixel's two samples and three additional samples from adjacent pixels. The sample pattern is analogous to the 5 pattern on a die. The quality of this technique is widely regarded as comparable to 4 sample multisampling.
