-- == Description
--
-- This extension allows an application to specify areas of the render
-- target where the fragment shader may be invoked fewer times. These
-- fragments are broadcasted out to multiple pixels to cover the render
-- target.
--
-- The primary use of this extension is to reduce workloads in areas where
-- lower quality may not be perceived such as the distorted edges of a lens
-- or the periphery of a user’s gaze.
