Subject: [PATCH] give our events model the option of allowing events to fall
 through so that they can be picked up in lower layers. change the panzoombar
 and the mousetoolbar to use this new fallthrough option so that we aren't
 causing bugs when the drag zoom rectangle gets dropped over them, they dont
 freak out. next up i am going to re-fix the popup events code to use this
 feature.
