eat up cpu time.
in fact it was in pre-ghost blender already.
works now for all posix OS's, except for windows. now working on getting
that fixed as well. until then, rendering will be slow at win32...
cvS: ----------------------------------------------------------------------
confusing functions which were only used once.
Part of examining how renderwindows get opened/closed, and to enable
a third option for render output to ImageWindow in Blender
- drawXXXspace, changeXXXspace, and winqreadXXXspace now receive the area
and spacedata as explicit arguments, allowing them to access private
data w/o going through globals.
- pass the new BWinEvent through to the winqreadXXXspace, allowing future
access to extended event data.
Removed direct calls to winqreadXXXspace to simulate user actions, replaced
by calls to action functions in edit.c or the appropriate handler.
