* there was a complete mixup of "drawing origin" and "scrolling offset" in the

Browse Source 
BView implementation (client side)
* introduced some private methods for _Convert*(BPoint*) methods which avoid
  doing the check_lock() thing in the recursion, also Origin() would likely
  have communicated with the app_server all the time, since the origin bit
  was needlessly invalidated, so some speedup should be achieved
* this should fix ticket #98
