Experiment with setting the dimensions of the second text box for multi-line optimal sizing.
Beginning of new idea using calculated maximum font size.
More progress on experiment.  Need to finish non-trivial case.
Finished implementation of experiment. Ready for testing.
Another variation of experiment that doesn't work.
More progress made by forcing shrinkFactor to be less than one. Still not there yet.
Working on brand new approach.  Not finished yet.
Finished new approach. Ready for testing.
Added second rendering of textbox and bounds getting to calculate optimal size in multi-line situations.
Changed default adjustment factor to 0.97 to accomodate a test case.
