'''OpenGL extension AMD.framebuffer_sample_positions
This module customises the behaviour of the
OpenGL.raw.GL.AMD.framebuffer_sample_positions to provide a more
Python-friendly API
Overview (from the spec)
In unextended GL, the sub-pixel loations of multisampled textures and
renderbuffers are generally determined in an implementation dependent
manner. Some algorithms -- in particular custom antialiasing functions --
depend on the knowledge of, or even require control over the positions of
samples within each pixel.
The AMD_sample_positions extension added some control over the positions
of samples within a single framebuffer. However, it forced all pixels
within a framebuffer to have the set of sample positions.
This extension provides a mechanism to explicitly set sample positions for
a framebuffer object with multi-sampled attachments in a repeating pattern,
allowing different pixels to use different sub-pixel locations for their
samples. The sample locations used by the FBO can be fixed for all pixels
in the FBOs attachments or they can be fixed for a sampling pattern
comprised of multiple pixels, where the sampling pattern is repeated over
all pixels. The rate of repeat of this sampling pattern size itself is
fixed and is implementation-dependent.
The official definition of this extension is available here:
