Update of /cvsroot/gaim/gaim/src
In directory sc8-pr-cvs1:/tmp/cvs-serv15053/src
Modified Files:
gtkblist.c gtkblist.h
Log Message:
This is fun. I got silly and decided to add some drop shadows to the buddy
list tooltip. It looks totally awesome. It will be reverted before the next
release though. It's just far too hacky.
