OpenGL ES Extension #131

OpenGL ES 2.0 is required.

Written based on the wording of the OpenGL ES 2.0 specification.

NVIDIA's SDK contains an offline shader compiler. This extension provides
a binary format to allow loading the resulting shader binaries into
OpenGL ES.

None.

Accepted by the <binaryFormat> parameter of ShaderBinary:

    NVIDIA_PLATFORM_BINARY_NV                        0x890B

Add the following paragraph to the end of section 2.10.2:

"NVIDIA_PLATFORM_BINARY_NV is returned when querying the list of
SHADER_BINARY_FORMATS.

Pre-compiled shader binaries in this format may be loaded via ShaderBinary.    
A binary in NVIDIA_PLATFORM_BINARY_NV format encodes a single vertex or
fragment shader.

When a binary fails to load, an INVALID_VALUE error is generated and a
more detailed error message is appended to the shader's info log."

INVALID_VALUE is generated if the <n> parameter to ShaderBinary is not 1.

INVALID_VALUE is generated if the <binary> parameter to ShaderBinary was
produced with an incompatible version of the NVIDIA shader compiler.

None.
