/**
* Native bindings to the ARB_texture_multisample extension.
*
* This extension provides support for two new types of "multisample textures" - two-dimensional and two-dimensional array - as well as mechanisms to
* fetch a specific sample from such a texture in a shader, and to attach such textures to FBOs for rendering.
*
* This extension also includes the following functionality, first described in NV_explicit_multisample:
*
*
* - A query in the API to query the location of samples within the pixel
* - An explicit control for the multisample sample mask to augment the control provided by SampleCoverage
*
*
* Promoted to core in {@link GL32 OpenGL 3.2}.
