When I call
RulerProvider.setUnits(RulerProvider.UNIT_CENTIMETERS) or
RulerProvider.setUnits(RulerProvider.UNIT_INCHES)
my horizontal and vertical rulers do not visually show Centimeters or
Inches. There is just a '0' on one end, and the rest of the ruler is
blank (white). UNIX_PIXELS works great. I added a RulerChangeListener,
and I know that notifyUnitsChanged() is being called with the new units
value. I have code identical to LogicRulerProvider in the logic
example. Why aren't my rulers rendering correctly?
