Add GL_ANGLE_robust_fragment_shader_output. This extension codifies expected behaviour on Android, where some applications don't declare shader outputs that are active with the Framebuffer.

Copyright terms at http://www.khronos.org/registry/speccopyright.html Status Draft Version Version 1, October 15, 2021 Number OpenGL ES Extension #?? Dependencies Requires OpenGL ES 3.0 Written against the OpenGL ES 3.2 specification. Overview This extension allows the OpenGL context to indicate if it supports rendering defined pixel values when there's an interface mismatch between the fragment shader and the draw framebuffer. New Procedures and Functions None New Tokens Accepted by the <cap> parameter to IsEnabled and the <pname> parameter to GetBooleanv, GetIntegerv, GetFloatv, and GetInteger64v: ROBUST_FRAGMENT_SHADER_OUTPUT_ANGLE 0x96B9 Additions to the OpenGL ES Specification Add to the end of section 15.2.1 "Selecting Buffers for Writing" If the fragment shader does not declare output variables that would be written to a bound draw buffer, the contents of the bound draw buffer remain unchanged.
