--
-- == Description
--
-- This extension allows an application to specify a negative viewport
-- height. The result is that the viewport transformation will flip along
-- the y-axis.
--
-- -   Allow negative height to be specified in the
--     'Vulkan.Core10.Pipeline.Viewport'::@height@ field to perform
--     y-inversion of the clip-space to framebuffer-space transform. This
--     allows apps to avoid having to use @gl_Position.y = -gl_Position.y@
--     in shaders also targeting other APIs.
--
-- == Obsoletion by @VK_KHR_maintenance1@ and Vulkan 1.1
--
-- Functionality in this extension is included in @VK_KHR_maintenance1@ and
-- subsequently Vulkan 1.1. Due to some slight behavioral differences, this
-- extension /must/ not be enabled alongside @VK_KHR_maintenance1@, or in
-- an instance created with version 1.1 or later requested in
-- 'Vulkan.Core10.DeviceInitialization.ApplicationInfo'::@apiVersion@.
