'''OpenGL extension NV.multisample_coverage
This module customises the behaviour of the
OpenGL.raw.WGL.NV.multisample_coverage to provide a more
Python-friendly API
Overview (from the spec)
The ARB_multisample extension provides a mechanism for antialiasing
primitives. This mechanism allows an application to request an
additional buffer, the multisample buffer, that is added to the
framebuffer. An application can request the number of samples per
fragment that are stored in the multisample buffer. Rendering
proceeds by writing color, depth, and stencil values for each
sample to the multisample buffer. The results are automatically
resolved to a single displayable color each time a pixel is
updated.
Coverage Sample Anti-Aliasing (CSAA) is an extension to multisample
antialiasing. The technique separates "samples" into two types of
samples. "Color samples" are samples with color, depth, and
stencil information stored in the multisample buffer. "Coverage
samples" include both color samples and additional samples that only
provide pixel coverage information.
This extension follows the example of the
NV_framebuffer_multisample_coverage extension, which adds CSAA
support for framebuffer objects. The base description of
multisample rendering is written in terms of coverage samples and
color samples. The windows system notion of "samples"
(SAMPLES_ARB) is layered on top of coverage and color samples.
The official definition of this extension is available here:
