/** Packaging design:
- The basic mesa ($out) contains headers and libraries (GLU is in mesa_glu now).
This or the mesa attribute (which also contains GLU) are small (~ 2 MB, mostly headers)
and are designed to be the buildInput of other packages.
- DRI drivers are compiled into $drivers output, which is much bigger and
depends on LLVM. These should be searched at runtime in
"/run/opengl-driver{,-32}/lib/*" and so are kind-of impure (given by NixOS).
(I suppose on non-NixOS one would create the appropriate symlinks from there.)
- libOSMesa is in $osmesa (~4 MB)
