Increasing window resize corner in Ubuntu 12.04

Resizing a window in Unity/Ubuntu 12.04 is quite a pain as one needs to target the 1 pixel border of the lower right corner. Fortunately the width can be increased:

Edit /usr/share/themes/Ambiance/metacity-1/metacity-theme-1.xml

and increase the widths, i.e.:

  <distance name="left_width" value="8"/>
  <distance name="right_width" value="8"/>
  <distance name="bottom_height" value="8"/>

Log out and in again.
