Finish implementation of distortion shader about distortionizer

[rpavlik]

Is an HLSL (for DirectX) version also feasible?

I don't see why not. I don't know DirectX, so am probably not the person to do this. Always glad to learn new things...

I also need an HLSL version of the distortion shaders for OSVR-MonoGame. Preferably in the form of a .fx file with the technique defined as well.

OsvrDistortion.shader in the Unity project should be very close to an HLSL version. Unity shaders use Cg, which is almost syntactically identical to HLSL. Maybe just remove the lines with CGINCLUDE, CGPROGRAM, etc..
