'''OpenGL extension EXT.raster_multisample
This module customises the behaviour of the
OpenGL.raw.GL.EXT.raster_multisample to provide a more
Python-friendly API
Overview (from the spec)
This extension allows rendering to a non-multisample color buffer while
rasterizing with more than one sample. The result of rasterization
(coverage) is available in the gl_SampleMaskIn[] fragment shader input,
multisample rasterization is enabled for all primitives, and several per-
fragment operations operate at the raster sample rate.
When using the functionality provided by this extension, depth, stencil,
and depth bounds tests must be disabled, and a multisample draw
framebuffer must not be used.
A fragment's "coverage", or "effective raster samples" is considered to
have "N bits" (as opposed to "one bit" corresponding to the single color
sample) through the fragment shader, in the sample mask output, through
the multisample fragment operations and occlusion query, until the coverage
is finally "reduced" to a single bit in a new "Coverage Reduction" stage
that occurs before blending.
The official definition of this extension is available here:
