OpenGL extension SGIX.resample
This module customises the behaviour of the OpenGL.raw.GL.SGIX.resample to provide a more Python-friendly API
Overview (from the spec)
This extension enhances the unpacking resampling capabilities of the SGIX_subsample extension.
When pixel data is received from the client and an unpacking upsampling mode other than PIXEL_SUBSAMPLE_RATE_4444_SGIX is specified, the upsampling is performed via one of two methods: RESAMPLE_REPLICATE_SGIX, RESAMPLE_ZERO_FILL_SGIX. Replicate and zero fill are provided to give the application greatest performance and control over the filtering process.
However, when pixel data is read back to the client and a packing downsampling mode other than PIXEL_SUBSAMPLE_RATE_4444_SGIX is specified, downsampling is performed via simple component decimation (point sampling). That is, only the RESAMPLE_DECIMATE_SGIX is valid.
