Ton Roosendaal 167ac3606b 2.5 
- Made view2d manipulations redraw on area level
- simplified call to send Notifiers:

  WM_event_add_notifier(bContext *C, int type, int value, void *data)

  This brings back more control to WM, no context messing within
  operators. :) Handlers that execute operators will be responsible
  for delivering correct contextes.

  In general: should lead to making context not exposed, but only 
  readable via some callbacks.
