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