[observer] Windows double buffer fixes
DC's and GC's is not double buffered by default on windows, and there is a separate erase event which causes awful flickering when constant updating a window. Hack around wx (to be able to use wxBufferPaintDC), to avoid flickering on windows. This works on windows because there (and only there) wxGC:create/1 also takes a memoryDC as argument.
