Native bindings to the NV_query_resource extension.

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.

Requires OpenGL 2.0.
