-----------------------------------------

             Summary: Inconsistencies with font measurement on some platforms
                 Key: PIVOT-1060
                 URL: https://issues.apache.org/jira/browse/PIVOT-1060
             Project: Pivot
          Issue Type: Bug
          Components: wtk-terra
         Environment: Windows 10 with 18 pt FontUtilities.MONOSPACED_FONTS (which could be
any of "Courier", "Courier New", "Andale Mono", "Monaco", "Menlo", or "MONOSPACED" depending
on platform).
            Reporter: Roger Lee Whitcomb
            Assignee: Roger Lee Whitcomb
             Fix For: 2.1.0


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.
