OpenGL extension NV.copy_image
This module customises the behaviour of the OpenGL.raw.GLX.NV.copy_image to provide a more Python-friendly API
Overview (from the spec)
This extension enables efficient image data transfer between image objects (i.e. textures and renderbuffers) without the need to bind the objects or otherwise configure the rendering pipeline. The WGL and GLX versions allow copying between images in different contexts, even if those contexts are in different sharelists or even on different physical devices.
