'''OpenGL extension OES.gpu_shader5
This module customises the behaviour of the
OpenGL.raw.GLES2.OES.gpu_shader5 to provide a more
Python-friendly API
Overview (from the spec)
This extension provides a set of new features to the OpenGL ES Shading
Language and related APIs to support capabilities of new GPUs, extending
the capabilities of version 3.10 of the OpenGL ES Shading Language.
Shaders using the new functionality provided by this extension should
enable this functionality via the construct
#extension GL_OES_gpu_shader5 : require (or enable)
This extension provides a variety of new features for all shader types,
including:
* support for indexing into arrays of opaque types (samplers,
and atomic counters) using dynamically uniform integer expressions;
* support for indexing into arrays of images and shader storage blocks
using only constant integral expressions;
* extending the uniform block capability to allow shaders to index
into an array of uniform blocks;
* a "precise" qualifier allowing computations to be carried out exactly
as specified in the shader source to avoid optimization-induced
invariance issues (which might cause cracking in tessellation);
* new built-in functions supporting:
* fused floating-point multiply-add operations;
* extending the textureGather() built-in functions provided by
OpenGL ES Shading Language 3.10:
* allowing shaders to use arbitrary offsets computed at run-time to
select a 2x2 footprint to gather from; and
* allowing shaders to use separate independent offsets for each of
the four texels returned, instead of requiring a fixed 2x2
footprint.
The official definition of this extension is available here:
