test-text-perf: Scale the text if the settings will not fit

Browse Source 
If the font size or the number of characters causes the label not to
fit on the stage, instead of aborting it will now scale the labels so
that it fits within one of the dimensions. This makes it easier to
test with large glyph sizes.
