It was working on Linux.. but not on Windows.. some issue with threads (openMP) and wxWidgets... I will fix it latter..

I can confirm that slower rendering time also in OpenGL in win8-64b-wx3.02, but just the first time, after the cache is built the rendering time is much faster (about 1/10) Anyway I think it would be useful to fix also the first rendering time about the improvement for the "pivot and rotation center", I think at the moment the pivot is just fine; kicad is not a MCAD sw, so for inspecting the board and parts, the actual implementation is just much better the previous one with a fixed centered pivot... Just a feedback on release 5921... in win8-64b-wx3.02 I get the rendering hanging and the progress status locked to 25%... also waiting looong time I don't get any rendering out ...
