-Subject: [PATCH] GLES2: Get sin/cos out of vertex shader
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The only place angle is activated and causes effect is RenderCopyEx. All other
-methods which use vertex shader, leave angle disabled and cause useless sin/cos
-calculation in shader.
-
-To get around shader's interface is changed to a vector that contains results
-of sin and cos. To behave properly when disabled, cos value is set with offset
--1.0 making 0.0 default when deactivated.
-
-As nice side effect it simplifies GLES2_UpdateVertexBuffer: All attributes are
-vectors now.
-
-Additional background:
-
-* On RaspberryPi it gives a performace win for operations. Tested with
-  [1] numbers go down for 5-10% (not easy to estimate due to huge variation).
-* SDL_RenderCopyEx was tested with [2]
-* It works around left rotated display caused by low accuracy sin implemetation
-  in RaspberryPi/VC4 [3]
-
-Upstream-Status: Accepted [4]
