/*
* Table to map typed characters to their Java virtual key equivalent and back.
* We use the incoming unichar (ignoring all modifiers) and try to figure out
* which virtual key code is appropriate. A lot of them just have direct
* mappings (the function keys, arrow keys, etc.) so they aren't a problem.
* We had to do something a little funky to catch the keys on the numeric
* key pad (i.e. using event mask to distinguish between period on regular
* keyboard and decimal on keypad). We also have to do something incredibly
* hokey with regards to the shifted punctuation characters. For examples,
* consider '&' which is usually Shift-7. For the Java key typed events,
* that's no problem, we just say pass the unichar. But for the
* KeyPressed/Released events, we need to identify the virtual key code
* (which roughly correspond to hardware keys) which means we are supposed
* to say the virtual 7 key was pressed. But how are we supposed to know
* when we get a punctuation char what was the real hardware key was that
* was pressed? Although '&' often comes from Shift-7 the keyboard can be
* remapped! I don't think there really is a good answer, and hopefully
* all good applets are only interested in logical key typed events not
* press/release. Meanwhile, we are hard-coding the shifted punctuation
* to trigger the virtual keys that are the expected ones under a standard
* keymapping. Looking at Windows & Mac, they don't actually do this, the
* Mac seems to just put the ascii code in for the shifted punctuation
* (which means they actually end up with bogus key codes on the Java side),
* Windows I can't even figure out what it's doing.
