Looks good :)

May be implement something like VISUAL_PLUGIN_FLAG_SPECIAL but
in an opposite way. I.e. plugin must be used only with this
application. This application simply provide some kind of
special data/interfaces that can not be used with Libvisual.

One nice way to implement this is to use const char* identifier
to specify, say, application id. Numeric id's -- enums and
#defines not very useful here, I think.

We could place this id to VisPluginInfo. If so, we should add
some void *dummys[5]; so we can extend functionality further
without breaking plugin ABI.
