  Log:
  Orange: fix for threaded rendering. Discovered that for some reason the
  threads didn't seem to free allocated memory... while rendering an long
  sequence, the 'virtual memory' size grew with about 20 meg per frame.
  This appeared to be not related to using malloc in threads (works
  properly), but just because threads were not closed properly.
  
  I assumed that the call to SDL_CreateThread() also closes the thread
  when finished... but that seems to be not the case. By using a call to
  SDL_WaitThread() after the thread was finished the memory heap is stable
  again.
  
  This is something I've seen not documented anywhere... the SDL man
  pages are horrible sparse; Take for example the official page:
