'''OpenGL extension OML.resample
Overview (from the spec)
This extension enhances the resampling capabilities of the
OML_subsample extension. It is loosely based on the SGIX_resample
extension.
When converting data from subsampled to uniform sampling, upsampling
may be performed by one of three methods: component replication,
zero fill, or adjacent neighbor averaging.
When converting data from uniform sampling to subsampled form,
downsampling may be performed only by component decimation (point
sampling) or averaging.
Upsampling and downsampling filters other than those defined by this
extension may be performed by appropriate use of convolution and
other pixel transfer operations. The zero fill unpacking mode is
included to assist applications wanting to define their own filters.
The official definition of this extension is available here:
