This extension provides additional orthogonally aligned “discard rectangles” specified in framebuffer-space coordinates that restrict rasterization of all points, lines and triangles.
From zero to an implementation-dependent limit (specified by
maxDiscardRectangles) number of discard rectangles can be operational
When one or more discard rectangles are active, rasterized fragments can
either survive if the fragment is within any of the operational discard
VK_DISCARD_RECTANGLE_MODE_INCLUSIVE_EXT mode) or be
rejected if the fragment is within any of the operational discard rectangles
These discard rectangles operate orthogonally to the existing scissor test functionality. The discard rectangles can be different for each physical device in a device group by specifying the device mask and setting discard rectangle dynamic state.
