'''OpenGL extension QCOM.shader_framebuffer_fetch_noncoherent
This module customises the behaviour of the
OpenGL.raw.GLES2.QCOM.shader_framebuffer_fetch_noncoherent to provide a more
Python-friendly API
Overview (from the spec)
Existing extensions such as EXT_shader_framebuffer_fetch and
ARM_shader_framebuffer_fetch_depth_stencil allow fragment
shaders to read existing framebuffer color or depth/stencil data as input.
This extension adds support for reading those same inputs with
relaxed coherency requirements. This mode can avoid expensive
per-primitive flushes of the pixel pipeline and may offer performance
improvements in some implementations.
When the relaxed coherency mode is enabled, reads of the framebuffer data
by the fragment shader will guarantee defined results only if each sample
is touched no more than once in any single rendering pass. The command
FramebufferFetchBarrierQCOM() is provided to indicate a boundary between
passes.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/QCOM/shader_framebuffer_fetch_noncoherent.txt
