Keyboard Handling

[Alexander Gottwald]

Hi,

I've tried some code to handle AltGr more correctly. 
I attached a patch to the winwndproc.c from Apr-14 Sourceball
which fixes at least the press of AltGr (the release is not done yet).

It uses mainly the good fact, that the fake Control_L- and Alt_R-message
have the same timestamp. I just cache the Control_L press, set a very 
short timestamp and 
1) drop the Control_L if the coresponding Alt_R message arrives 
2) send the Control_L if 
    a) another key (not Alt_Gr) was pressed
    b) the timeout (currently 1ms) expires

The current code still needs to be cleaned up, but hope you can already
give some hints on possible error and mistakes.
    
I will make a test version available on http://www.gotti.org/ [1].

bye
