/**
 * Native bindings to the EXT_raster_multisample extension.
 * 
 * This extension allows rendering to a non-multisample color buffer while rasterizing with more than one sample. The result of rasterization (coverage)
 * is available in the gl_SampleMaskIn[] fragment shader input, multisample rasterization is enabled for all primitives, and several per- fragment
 * operations operate at the raster sample rate.
 * 
 * When using the functionality provided by this extension, depth, stencil, and depth bounds tests must be disabled, and a multisample draw framebuffer
 * must not be used.
 * 
 * A fragment's "coverage", or "effective raster samples" is considered to have "N bits" (as opposed to "one bit" corresponding to the single color
 * sample) through the fragment shader, in the sample mask output, through the multisample fragment operations and occlusion query, until the coverage is
 * finally "reduced" to a single bit in a new "Coverage Reduction" stage that occurs before blending.
 * 
 * Requires {@link GLES30 GLES 3.0}.
