'''OpenGL extension QCOM.texture_foveated_subsampled_layout
This module customises the behaviour of the
OpenGL.raw.GLES2.QCOM.texture_foveated_subsampled_layout to provide a more
Python-friendly API
Overview (from the spec)
This extension builds on QCOM_texture_foveated by introducing a new foveation
method bit that aims to reduce memory bandwidth by avoiding the upscaling that
occurred as part of the original extension.
With the original FOVEATION_SCALED_BIN_METHOD_BIT_QCOM foveation method,
the render target in system memory is entirely populated. The lower
resolution framebuffer data is upscaled to fill the entire render target.
The subsampled layout method introduced in this extension leaves the
framebuffer data at the calculated lower density and instead samples
directly from the the lower resolution texels.
The primary usecase this is targeting is traditional VR pipeline. The
application eye buffers would be rendered as textures with a subsampled layout
and then sampled by the warp process. Sampling from a texture with a
subsampled layout requires a new sampler layout qualifier.
The official definition of this extension is available here:
