'''OpenGL extension NV.conservative_raster_pre_snap_triangles
This module customises the behaviour of the
OpenGL.raw.GL.NV.conservative_raster_pre_snap_triangles to provide a more
Python-friendly API
Overview (from the spec)
When CONSERVATIVE_RASTERIZATION_NV is enabled, the fragments generated for
a primitive are conservative with respect to the primitive after snapping
to sub-pixel grid. This extension provides a new mode of rasterization
for triangles where the fragments generated are conservative with respect
to the primitive at infinite precision before vertex snapping.
When the conservative raster mode is set to CONSERVATIVE_RASTER_MODE_PRE_-
SNAP_TRIANGLES, triangles are rasterized more conservatively, and may
generate fragments not generated when the mode is CONSERVATIVE_RASTER_MODE_-
POST_SNAP (default). In particular it may generate fragments for pixels
covered by triangles with zero area, or for pixels that are adjacent to
but not covered by any triangle. This modified behavior may be useful in
compensating for rounding errors caused by snapping vertex positions to a
sub-pixel grid during rasterization. It's possible that a non-degenerate
triangle becomes degenerate due to snapping. It's additionally possible
that rounding errors in computing the position of a vertex or from
snapping may cause a primitive that would cover a pixel at infinite
precision to fail to cover the pixel post-snap. Rasterizing such
primitives more conservatively may be useful for "binning" algorithms
described in NV_conservative_raster.
