OpenGL extension EXT.packed_pixels
This module customises the behaviour of the OpenGL.raw.GL.EXT.packed_pixels to provide a more Python-friendly API
Overview (from the spec)
This extension provides support for packed pixels in host memory. A packed pixel is represented entirely by one unsigned byte, one unsigned short, or one unsigned integer. The fields with the packed pixel are not proper machine types, but the pixel as a whole is. Thus the pixel storage modes, including PACK_SKIP_PIXELS, PACK_ROW_LENGTH, PACK_SKIP_ROWS, PACK_IMAGE_HEIGHT_EXT, PACK_SKIP_IMAGES_EXT, PACK_SWAP_BYTES, PACK_ALIGNMENT, and their unpacking counterparts all work correctly with packed pixels.
