OpenGL extension ARB.texture_storage_multisample
This module customises the behaviour of the OpenGL.raw.GL.ARB.texture_storage_multisample to provide a more Python-friendly API
Overview (from the spec)
The ARB_texture_storage extension and OpenGL 4.2 introduced the concept of immutable texture objects. With these objects, once their data store has been sized and allocated, it could not be resized for the lifetime of the objects (although its content could be updated). OpenGL implementations may be able to take advantage of the knowledge that the underlying data store of certain objects cannot be deleted or otherwise reallocated without destruction of the whole object (normally, a much heavier weight and less frequent operation). Immutable storage for all types of textures besides multisample and buffer textures was introduced by ARB_texture_storage. For completeness, this extension introduces immutable storage for multisampled textures.
The official definition of this extension is available here:


glTexStorage2DMultisample( target , samples , internalformat , width , height , fixedsamplelocations )
glTexStorage3DMultisample( target , samples , internalformat , width , height , depth , fixedsamplelocations )
