/**
 * Native bindings to the NV_primitive_shading_rate extension.
 * 
 * This extension builds on top of the {@code NV_shading_rate_image} extension to provide OpenGL API support for using a per-primitive shading rate value
 * to control the computation of the rate used to process each fragment.
 * 
 * In the {@code NV_shading_rate_image} extension, the shading rate for each fragment produced by a primitive is determined by looking up a texel in the
 * bound shading rate image and using that value as an index into a shading rate palette. That extension provides a separate shading rate image lookup
 * enable and palette for each viewport. When a primitive is rasterized, the implementation uses the enable and palette associated with the primitive's
 * viewport to determine the shading rate.
 * 
 * This extension decouples the shading rate image enables and palettes from viewports. The number of enables/palettes now comes from the
 * implementation-dependent constant {@link #GL_SHADING_RATE_IMAGE_PALETTE_COUNT_NV SHADING_RATE_IMAGE_PALETTE_COUNT_NV}. When {@code SHADING_RATE_IMAGE_PER_PRIMITIVE_NV} (added here) is enabled, the
 * value of the new {@code gl_ShadingRateNV} built-in output is used to select an enable and palette to determine the shading rate. Otherwise, the
 * viewport number for the primitive is used, as in {@code NV_shading_rate_image}.
 * 
 * Requires {@link GLES32 GLES 3.2}.
