--
-- == Description
--
-- This extension exposes a hardware feature used by some vendors to
-- implement OpenGL’s dithering. The purpose of this extension is to
-- support layering OpenGL over Vulkan, by allowing the layer to take
-- advantage of the same hardware feature and provide equivalent dithering
-- to OpenGL applications.

--
-- == Issues
--
-- 1) In OpenGL, the dither state can change dynamically. Should this
-- extension add a pipeline state for dither?
--
-- __RESOLVED__: No. Changing dither state is rarely, if ever, done during
-- rendering. Every surveyed Android application either entirely disables
-- dither, explicitly enables it, or uses the default state (which is
-- enabled). Additionally, on some hardware dither can only be specified in
-- a render pass granularity, so a change in dither state would necessarily
-- need to cause a render pass break. This extension considers dynamic
-- changes in OpenGL dither state a theoretical situation, and expects the
-- layer to break the render pass in such a situation without any practical
-- downsides.
