Fixed case sensitivity problem Fixed clang compiler problem with having the class namespace used in an inline for the == operator Tweaked some theme stuff to be more consistent. Added initial test of no-pie for linux test sidestep of getTexCoord in shadergen hlsl feature so we don't assert when getting the terrain's shaderstuffs(which uses float3 instead of normal float2)
