/**
 * Native bindings to the NV_mesh_shader extension.
 * 
 * This extension provides a new mechanism allowing applications to use two new programmable shader types -- the task and mesh shader -- to generate
 * collections of geometric primitives to be processed by fixed-function primitive assembly and rasterization logic. When the task and mesh shaders are
 * drawn, they replace the standard programmable vertex processing pipeline, including vertex array attribute fetching, vertex shader processing,
 * tessellation, and the geometry shader processing.
 * 
 * Requires {@link GLES32 GLES 3.2}.
