Fixed and checked in.  The code is miles simpler and still seems to
generate the same results.  I've also added a GetBoundingBox() call
and tested everything on Windows and Linux.

My next problem is the texture clipping on the left side.  See the
test images for example:

The 0 on the left is clipped with a vertical edge.  Somewhere inside
of vtkFreeTypeUtilities things need to be offset to account for the
freetype anti-aliasing (I think).  Does anyone have any tips on this
