PuTTy CAN shape now

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

i guess this time, the subject really applies...
because PuTTy is now actually doing the shaping itself.... :))

since noone seemed to be helping me much, i took the liberty of taking VIM's 
arabic shaping
code, and stuck it into PuTTY... the authors as the code says are Nadim 
Shaikli and Isam Bayazidi..
if the authors have any problem with that, i'll remove the code (now, i know 
how shaping is done)
and probably rewrite it again...

i have a few points though to the authors...
- Combinations = Ligatures = Lam Alef ... ???
- there is a problem with a_LAM when its not isolated, either way it doesnt 
get translated to
 Form-B, i think the second parameter of the function A_firstc_laa() is the 
problem...
 i think i call it with a wrong value... Can u tell me whats the composing 
char..?? or maybe you
 can explain arabic_shape() 's params...?
- i took a function from VIM with arabic.h and arabic.c... the function 
utf_ptr2char()... is there
 a problem with that..? i can remove it, and write my own OR i can include 
credit to VIM's author.
- your names will be on the top of the files, but i want to remove VIM's 
credits, and put PuTTy's..
 so, what do u think..??


anyway, i read on the mailing list archives that the author of friBidi 
wouldnt let us use it, so i
wrote a function that just flips any 0x0600 chars in place....

musab we dont have to change the font's script anymore... u just use UTF-8 
and
GetCharacterPlacementW()... <-- notice the W in the name... it means Unicode 
implementation...

only a few small things are left to deal with...
- char spacing is messed up... does any1 know anything about that...?
- a problem with Lam... doesnt get translated to Form-B and stays 0x0644...
- cursor position doesnt change when i use the arrows... is it a PuTTy 
thing..??
- when typing the same char repeatedly, it doesnt shape... when i force a 
redraw (ex. minimise
 and maximise) it shapes..
- someone to test it...
- do we contact PuTTy's author now or do we test it first...?
- do we get a CVS account, and commit this stuff..??
- do we get to change the ToDo list...?? :)))
- the code is a bit messy and needs to be cleaned up...
- do we need to add #define and #ifdef to the code, or do we leave arabic 
turned on
 all the time (ask PuTTy's author)

btw, im new here and dont know who to contact about CVS, and the ToDo...

ak...
