i have a map view that draws (in the worst case) around 100 overlay
items. when the user tries to zoom / scroll the map, it's slow for
obvious reasons. i'm already caching as much as i can in draw(), but
because the zoom level, and consequently the location where things are
drawn changes, there's a limit. also, it seems like the "drawXXX()"
methods are what's taking up the time. i understand there's a "view caching" mechanism, but i can find little information on how to use it. can anyone point me to some example code, or otherwise give me some pointers? thanks. --
