- removed POT texture size from shadow mask in HLSL, U/V size is now simply the percentage of the actual texture size
- adjusted display names of options
- separated curvature parameter into distortion, cubic_distortion and distort_corner
- distortion and cubic_distortion can be negative, to compensate each other
- distort_corner is intependent from the image distortion
