--
-- == Description
--
-- This extension adds a new rasterization mode called conservative
-- rasterization. There are two modes of conservative rasterization;
-- overestimation and underestimation.
--
-- When overestimation is enabled, if any part of the primitive, including
-- its edges, covers any part of the rectangular pixel area, including its
-- sides, then a fragment is generated with all coverage samples turned on.
-- This extension allows for some variation in implementations by
-- accounting for differences in overestimation, where the generating
-- primitive size is increased at each of its edges by some sub-pixel
-- amount to further increase conservative pixel coverage. Implementations
-- can allow the application to specify an extra overestimation beyond the
-- base overestimation the implementation already does. It also allows
-- implementations to either cull degenerate primitives or rasterize them.
--
-- When underestimation is enabled, fragments are only generated if the
-- rectangular pixel area is fully covered by the generating primitive. If
-- supported by the implementation, when a pixel rectangle is fully covered
-- the fragment shader input variable builtin called FullyCoveredEXT is set
-- to true. The shader variable works in either overestimation or
-- underestimation mode.
--
-- Implementations can process degenerate triangles and lines by either
-- discarding them or generating conservative fragments for them.
-- Degenerate triangles are those that end up with zero area after the
-- rasterizer quantizes them to the fixed-point pixel grid. Degenerate
-- lines are those with zero length after quantization.
