NSView change

[Fred Kiefer]

I just added all the new ivars to NSView. As nobody commented on the 
compacting of the bollean ivars I did leave them untouched. Also the 
coding/decoding of the new ivars is still missing. Remember that you 
will need to recompile all applications to be able to use this new code.

I think, that a next step would be to go through all the usage of 
lockFocus in GUI to see if a preceding call to canDraw would be needed. 
After this some of the scattered checks for the existence of the window, 
as in [NSCell drawWithFrame:inView:] could be removed.

Any comments on the change to NSView are welcome. Currently this is 
still something that could be undone.
