It would be great to breakout the GLES class that wraps OpenGL/WebGL in https://github.com/ziocroc/Ombra/blob/master/Graphics/Rendering/Ombra/Backend.hs. If this were a separate repo, other projects could use it (without depending on Ombra entirely). Either way, thanks!

Hello, I'm trying to build Ombra using ghcjs 0.2.1 with ghc 8.0.2. It builds fine up to commit 98b7089, but after that it complains about not having a cabal file for a handful of commits, then when the cabel file is added in a later commit the build fails with the following error:

    Cabal-simple_mPHDZzAJ_1.24.2.0_ghcjs-0.2.1.9008011_ghc-8.0.2: can't find
    source for Graphics/Rendering/Ombra/Backend/WebGL in .,
