Hi Dimitar,

Any plugin that is filetype specific must know which documents are its type.

I wouldn't expect (for example) GeanyLatex to interfere with my C#
programming.  Similarly I wouldn't expect the debugger plugin to try
to work on a language gdb doesn't understand, eg Java.

Maybe you should contact Matthew, during a conversation we had on IRC
he revealed a prototype for manageing all such limited resources, not
just markers, in a consistent manner.

Since the SC_MARK_AVAILABLE isn't, erm, available, for other recources
such as indicators, Matthew uses the suggested boolean map method.

@Frank, this would give a single consistent interface to acquire and
release all limited resources, markers, indicators, margins and
styles.

Cheers
Lex
