i am new in this svg batik world and am looking at some performance 
issues related to handling mouse events for an app that allows user 
mousemove events to render lines on the display.  i observe performance 
differences on a winxp laptop with mouse input vs. pen input on a winxp 
tablet; also performance diffs between pen and mouse on the same winxp 
tablet.

can someone educate me as to the granularity of how often the mousemove 
event triggers, how it varies across various platforms and input 
devices, and whether this is tunable?

on 
http://www.w3.org/TR/2000/REC-DOM-Level-2-Events-20001113/events.html#Events-eventgroupings-mouseevents 
i see

"The mousemove event occurs when the pointing device is moved while it 
is over an element. This event is valid for most elements."

TIA...
