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)
SDL2 wa still linking against dxerr.lib and dxerr8.lib but not actually
using any code that requires them. Both libs are deprecated and no
longer included in the Windows SDKs.
