OpenGL ES Extension #??

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.
