/**
 * Native bindings to the NV_framebuffer_multisample_coverage extension.
 * 
 * This extension extends the EXT_framebuffer_multisample specification by providing a new function, RenderBufferStorageMultisampleCoverageNV, that
 * distinguishes between color samples and coverage samples.
 * 
 * EXT_framebuffer_multisample introduced the function RenderbufferStorageMultisampleEXT as a method of defining the storage parameters for a multisample
 * render buffer. This function takes a {@code samples} parameter. Using rules provided by the specification, the  parameter is resolved to an actual
 * number of samples that is supported by the underlying hardware. EXT_framebuffer_multisample does not specify whether {@code samples} refers to coverage
 * samples or color samples.
 * 
 * This extension adds the function RenderbufferStorageMultisamplCoverageNV, which takes a {@code coverageSamples} parameter as well as a
 * {@code colorSamples} parameter. These two parameters give developers more fine grained control over the quality of multisampled images.
 * 
 * Requires {@link EXTFramebufferObject EXT_framebuffer_object}, {@link EXTFramebufferBlit EXT_framebuffer_blit} and {@link EXTFramebufferMultisample EXT_framebuffer_multisample}.
