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