In KstMatrix, it is possible for some elements to be infinite or NAN.

palette. This is confusing since invalid data will then have the same color
as normal data that is simply off-scale.
I think that the correct thing to do is to paint these pixels the current
background color (KstSettings::globalSettings()->backgroundColor).
Unfortunately this class is compiled into libkstapp, and I need to access it
from KstImage.cpp, which is in libkstmath.
What is the most technically correct way to make KstSettings available
