Update the documentation and organization of the scancodes.
The common scan codes were disjointed and logically belong together. Signed-off-by: Jeremy White <jwhite@codeweavers.com> Acked-by: Frediano Ziglio <fziglio@redhat.com>

** Converting keycodes to AT scancodes is very hard.
|

** luckly there are some resources on the web and in the Xorg driver that help
|
||||
** us figure out what browser dependent keycodes match to what scancodes.
|
||||
**
|
||||
** This will most likely not work for non US keyboard and browsers other than
|
||||
** modern Chrome and FireFox.
|
||||
** Converting browser keycodes to AT scancodes is very hard.
|
||||
** Spice transmits keys using the original AT scan codes, often
|
||||
** described as 'Scan Code Set 1'.
|
||||
** There is a confusion of other scan codes; Xorg synthesizes it's
|
||||
** own in the same atKeynames.c file that has the XT codes.
|
||||
** Scan code set 2 and 3 are more common, and use different values.
|
||||
** Further, there is no formal specification for keycodes
|
||||
** returned by browsers, so we have done our mapping largely with
|
||||
** empirical testing.
|
||||
** There has been little rigorous testing with International keyboards,
|
||||
** and this would be an easy area for non English speakers to contribute.
