96 libglvnd is a vendor-neutral dispatch layer for arbitrating OpenGL API
97 calls between multiple vendors. It allows multiple drivers from different
98 vendors to coexist on the same filesystem, and determines which vendor to
99 dispatch each API call to at runtime.
100 Both GLX and EGL are supported, in any combination with OpenGL and OpenGL ES.
