Text Selection Hack

[Thomas E Deweese <th...@kodak.com>]

Hi All,

   I put this hack togeather on the plane (I had mentioned an earier
version of this to Vincent at ApacheCON).  I'm not commiting it since
this sort of thing tends to be very personal, but for those that
want to try it out I've attached it as a unified context diff.

   It basically replaces the really ugly (but almost always visible)
XOR with a nice semi-transparent off-white rectangle with a white
border.  This almost always gives a nice results when selecting,
although in some cases it isn't as visible as one might want.

   Much of the diff is to 'fix' the TextSelectionManager so it pays
attention to it's own highlight bounds.
