/**
* Native bindings to the ARB_internalformat_query extension.
*
* OpenGL 4.1 has a number of queries to indicate the maximum number of samples available for different formats. These give a coarse-grained query
* mechanism e.g. an implementation can expose different sample counts for integer and floating-point formats, but not for different floating-point
* formats. There is also no convenient way for the user to determine the granularity of sample counts available, only the maximum.
*
* This extension adds a query mechanism that allows the user to determine which sample counts are available for a specific internal format.
*
* Requires {@link GL30 OpenGL 3.0} or {@link ARBFramebufferObject ARB_framebuffer_object}. Promoted to core in {@link GL42 OpenGL 4.2}.
