/**
 * Native bindings to the EXT_multi_draw_arrays extension.
 * 
 * These functions behave identically to the standard OpenGL 1.1 functions glDrawArrays() and glDrawElements() except they handle multiple lists of
 * vertices in one call. Their main purpose is to allow one function call to render more than one primitive such as triangle strip, triangle fan, etc.
