Roger Lee Whitcomb commented on PIVOT-1060:
-------------------------------------------
In the screenshots, the top "Results" field is TextArea, while bottom
"Expressions" is TextPane. It appears on Windows that the line spacing is
different between these two components, even using the exact same font, while
on OSX the line spacing is the same, and agrees with NumberRuler. Will get the
exact font metrics shortly for comparison.

> Using a (new) NumberRuler with both TextArea and TextPane shows
> inconsistencies (only on Windows that I can tell) between the font height and
> positioning between the ruler and the two components. Specifically:
> * with TextPane the numbers are ~1 pix lower in ruler than in text
> * with TextArea the numbers in ruler are same ~1 pix lower on normal lines,
> BUT on wrapped lines the TextArea seems to ignore leading so that the lines
> get higher and higher WRT ruler
> On OSX there seems to be none of the problems.
