Rik Hemsley abd2f3d6fd Textures for buttons too. Necessary now that titlebar can be large 
enough for you to see them. Oh yes, the titlebar now changes size
with your font size. See http://www.geoid.clara.net/silly.jpg for
a (silly) example of this. This is in fact an essential feature
IMO, for people who can't read titlebar text at the restricted
sizes that the other styles allow.

New funky iconify animation, but I haven't made it available via
a config key yet, so you can't use it :P
