'''OpenGL extension NV.query_resource
This module customises the behaviour of the
OpenGL.raw.GL.NV.query_resource to provide a more
Python-friendly API
Overview (from the spec)
OpenGL implementations manage the residence of textures, shaders, and
other graphical objects in GPU accessible memory (whether in on-board
video memory or addressable system memory is implementation dependent).
With more insight into OpenGL's memory usage 1) applications could make
educated decisions on better utilizing the limited GPU resources,
2) users could better optimize their workflow when working with multiple
tools, and 3) administrators can make better decisions regarding resource
allocation and system configurations.
The purpose of this extension is to return a more detailed breakdown
of memory usage in terms of the OpenGL objects residing in memory
(textures, render buffers, buffer objects, system reserved objects, ...).
This extension differs from GL_NVX_gpu_memory_info in that this extension
returns detailed memory usage at the object level for video memory while
the other extension only reports total vidmem usage.
For the purposes of this specification the term vidmem refers to video
memory resident on the graphics card that is directly accessible to the
GPU at the highest performance level.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/NV/query_resource.txt
