Description

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.
