that's exact what i told you, what openbox has: they say: if movement <
number_pixels then its click,
if movement >= pixels, its slide.
in your case, one could hava a hysteresis over the time: if a single
click comes shortly after a slide,
it is part of slide.
if you measure now the time of the tap, you have all you need for
differentiating between all this three events.
generally i think, its better to get the btn-release instead of
btn-down. (from the view of windowmanager)
and you are right: it should be done in tslib or window manager.
