yes. Perhaps 'horribly' was overstated ;) but the problem I perceive
is the drawing of each marker would go through the draw() process
which calls modifyAlphaImageDiv a couple of times, once in draw and
again in moveTo. I haven't profiled this but I'm sure it adds a few
milliseconds per marker to call this function and it seems wasteful to
duplicate it when you really just need to position the containing
element and let the developer position everything else statically
inside the containing element.
Another reason for not wanting to do individual markers is that I
would like to make the marker a bit more dynamic by adding some event
handlers (mouse over etc).
In ka-Map, the equivalent to the Marker/Icon combo was a method called
addObjectGeo which allowed you to place an HTML element at a
geographic location and have the location managed by the
'API' (including offsets from top/left etc) and I found this very
I'll create an enhancement ticket to solicit implementation suggestions.
