'''OpenGL extension NV.conservative_raster
This module customises the behaviour of the
OpenGL.raw.GLES2.NV.conservative_raster to provide a more
Python-friendly API
Overview (from the spec)
This extension adds a "conservative" rasterization mode where any pixel
that is partially covered, even if no sample location is covered, is
treated as fully covered and a corresponding fragment will be shaded.
A new control is also added to modify window coordinate snapping
precision.
These controls can be used to implement "binning" to a low-resolution
render target, for example to determine which tiles of a sparse texture
need to be populated. An app can construct a framebuffer where there is
one pixel per tile in the sparse texture, and adjust the number of
subpixel bits such that snapping occurs to the same effective grid as when
rendering to the sparse texture. Then triangles should cover (at least)
the same pixels in the low-res framebuffer as they do tiles in the sparse
texture.
The official definition of this extension is available here:
