Correct display of zero values with -logscale 1
In order to do that, improve the clipping functionality in tkbltGrMisc.C
to support infinite coordinates. It also now provides more information
with regards to its processing, letting tkbltGrElemLine.C use that same
routine instead of duplicade the clipping code.
