win32 zoom

 
I have spent several hours on implementing the win32 zoom using the
SetWindowExt and SetViewportExt functions, with the following
conclusions:

(1) I can see no difference at 200% zoom between the text scaled the
old way and the new way. I have noted similar craming of letters in
both, which makes me think that win32 does internally excatly the
same we do at the moment. (I would be curious to see if the same is
true of using the SetWorldTransform() function, but that is not
sufficiently portable.).

(2) While the changes seem to be limited to win32 files, there is a
huge potential for screwups -- the scroll and rulers stop working and
need to be fixed up, there are redraw issues, and who knows what
else.

=> Bottom line, I really do not want to meddle in this at this stage.

(I think the latter part of 7610 is, however, only fixed for the
Uniscribe graphics and not for the basic win32 graphics class -- I
still need to look into this).
