[21:26:45] <CountPillow> there isn't a funnier page on the internet than this packages.debian.org/source/testing/mesa
[21:26:59] <CountPillow> the headers for libegl-mesa0 are naturally in libegl1-mesa-dev
[21:28:51] <CountPillow> libgles2-mesa-dev? Is it the second epoch of libgles? Or is it libgles2? Whatever the case, it's a transitional dummy package.
[21:29:16] <CountPillow> libgl1-mesa-dri definitely is epoch 1 of libgl though, and not OpenGL 1.x
