Merge 3. Improve performance by switching to less aggressive settings for RI_NUM_TESSELLATED_SEGMENTS and RI_MAX_SAMPLES. Ignored the WIN32 specific API decoration defines when doing the merge. Note the code is now optimised in riPath.cpp to change from RI_NUM_TESSELLATED_SEGMENTS to _QUAD, _CUBIC, _ARC settings which are each now set to 8. SVG Tiger now renders in 5 seconds (15 seconds quicker). The quality of the OVG icons is slightly reduced but still very useable.
