test putty's shaping

["ahmad khalifa" <ahmadkhalifa at hotmail dot com>]

well, this time we need people to test putty also on Win2000 and WinXP...

shaping should be working almost fine BUT, you have to minimise and maximize 
for
the shaping to be done... i.e the characters will look broken, minimize the 
window and
then pull it back up, everything should look fine...
note: i have implemented a simple flipping function, that flips arabic chars 
so each
word's chars will be laid from R to L, but the words themselves from L to 
R...

the .exe is here
http://ahmadkhalifa.tripod.com/putty/putty.exe

some issues left...
- the redraw thing... (will ask Simon about.. although he said in his chat 
session that
 it should be done at the top of the big FOR loop.. between that and the 
display
 function inside the loop, all FEXX values are changed to 06XX !!!!)
- some chars' spacing is a bit bad.. (no big deal actually)
- Bidi support... (or should we just keep the flipping function..?)
- Backspacing deletes 4 chars at a time (will check later)
- when changing Lam-Alef to its coresponding Glyph, the Alef is left as it 
is
 and the value 06 is changed to FE... i.e the Alef is changed from 0627 to 
FE27, this
 way it doesnt appear... any 1 know how to deal with this..? keep in mind 
that i cant
 mess with the actual buffer, or the display buffer...
 should i just leave it as space..?? what if its Medial..? (will keep this 
issue for later)

i'll look at ICU, but i dont think it would benefit much, because its a 
large Library and
Simon wont like that... i do prefer the flipping function, maybe a better 
one that flips
the words too...

nadim, would you like to give him the update or do we wait for a reply to 
the
first letter..?

ak...
