Hi Brent,

it is interesting thing, but be aware that EventQueue performs some 
coalescing for PaitnEvents and for MouseEvents even if component doesn't 
coalesce them (see EventQueue.coalesceEvent()).
So, it will not be enough to add these methods to Componet.

I'd also leave this w/o changing, though someone may say that this is 
inconvenient for Swing (or other "strange" AWT-based libraries ;)
