Daniel M. Duley 0c77d7383e Trying to make the titlebar buttons easier to hit on laptops by increasing the 
width. The issue here is I want to make the buttons as wide as possible for
laptop mice without having the titlebar be all buttons and no title ;-) My
solution so far is making the common buttons bigger and the uncommon ones
smaller. It's not consistent but let's me make the areas frequently hit
wide as hell, which is good for a laptop :) Close, iconify, and maximize are
larger - sticky and help are smaller.

Another updated shot is at:
