[GD-General] Key handling revisited

[Brian H. <bri...@py...>]

After thinking about my key handling situation for a day, I think I finally 
stumbled upon the obvious solution.

Fundamentally I wasn't differentiating between ASCII characters and raw key 
codes, so I ended up just having a jumble of logic both on the key reading 
side (my platform driver) and on the application side.  My HEvent structure 
only had a keyCode member, which mapped to my system virtual key constants 
(directly taken from the VK_ constants in WINUSER.H so that there was a 
one-to-one mapping).

To simplify my life, I just added another field, evChar, which is the ASCII 
representation of the virtual key code.  So I can differentiate between top 
row "0", keypad "0", or just read an ASCII "0" depending on the needs of 
the calling routine.

Yeah, kinda duh, but for some reason I was just focused on having a single 
key code and doing the appropriate thing with it at all times.

Of course, this doesn't address the issue of international keyboards.  I 
have no idea what to do about that, other than just hope and pray it's not 
a problem.  And if it is, I guess I'll deal with it then.
