%description
This is a work-in-progress implementation of the vendor-neutral
dispatch layer for arbitrating OpenGL API calls between multiple
vendors on a per-screen basis, as described by Andy Ritger's OpenGL
ABI proposal:
<https://github.com/aritger/linux-opengl-abi-proposal/blob/master/linux-opengl-abi-proposal.txt>.

Currently, only the GLX window-system API and OpenGL are supported,
but in the future this library may support EGL and OpenGL ES as well.

%description -l pl.UTF-8
Ten pakiet to (będąca w trakcie tworzenia) implementacja warstwy
przekazującej wywołania dowolnych wywołań API OpenGL między różnymi
producentami w zależności od ekranu, zgodnie z propozycją opisaną
przez Andy Ritgera:
<https://github.com/aritger/linux-opengl-abi-proposal/blob/master/linux-opengl-abi-proposal.txt>.

Obecnie obsługiwane jest tylko API systemu okienek GLX oraz OpenGL, w
przyszłości biblioteka może obsługiwać także EGL i OpenGL ES.
