Panel plugin interface

[Maarten Boekhold]

Hi all,

Yesterday I asked for information on the panel plugin interface. On the 
suggestion of 'benny' on the #xfce IRC channel, I created a list of all 
the non-static functions in the panel source files (just the 'panel' 
sub-directory).

I suspect that a lot of those functions are not intended to be used by 
plugins, so I'd appreciate it if somebody could have a look at the list 
of files/functions included below, and comment on it. Perhaps mark all 
functions that are intended to be accessed by panel plugins with a '*'? 
That list could be included in the XFCE docs as a quick/dirty reference 
for plugin writers as well...

I'll also try to create a list of functions that a plugin is supposed to 
provide, and post that later.
