I tend to agree with Henrik here. Pluggable gesture recognizers is nice,
but I don't see it as a necessity or even something that will likely be
used very frequently. I think we should keep it in mind for a possible
revision to geis (2.1 maybe?), but not as a core piece of functionality
we should spend time on right now. I'm afraid we've already got too much
on our plate :).
