First Material Tests

Here are some material testss. The scratch texture must be hold separately and in much higher resolution. Rendering times in 32-bit were around 10 minutes (not saved in OpenEXR format) - standard lighting with HDRI environment (garden, outdoors) - no color correction. White should be more off - taking that into the shader.

Some reflection work for the balls - very carefully applied. Ball whites are taken to off-white improves the look greatly. Reducing accuracy on area shadows plus AA on 1x1,4x4 and 5% th gives an enormous speed up. Rendering time went down to 6:30.
