--
-- == Description
--
-- This extension adds support for an exclusive scissor test to Vulkan. The
-- exclusive scissor test behaves like the scissor test, except that the
-- exclusive scissor test fails for pixels inside the corresponding
-- rectangle and passes for pixels outside the rectangle. If the same
-- rectangle is used for both the scissor and exclusive scissor tests, the
-- exclusive scissor test will pass if and only if the scissor test fails.

--
-- == Issues
--
-- 1) For the scissor test, the viewport state must be created with a
-- matching number of scissor and viewport rectangles. Should we have the
-- same requirement for exclusive scissors?
--
-- __RESOLVED__: For exclusive scissors, we relax this requirement and
-- allow an exclusive scissor rectangle count that is either zero or equal
-- to the number of viewport rectangles. If you pass in an exclusive
-- scissor count of zero, the exclusive scissor test is treated as
-- disabled.
