Align baselines of 2 fields

[Niggemann, Bernd]

Hi Marty, 

depending how liberal you are in letting users choose fonts and sizes you might get "unexpected" results by aligning to field 1


try this stress test


---------------------------------
on mouseUp
   lock screen
   set the textfont of field 1 to any line of the fontNames
   set the textfont of field 2 to any line of the fontNames
   set the textSize of field 1 to random(20) + 10
   set the textSize of field 2 to random(20) + 10
  -- put the textFont of field 1 into field "Font1"
  -- put the textFont of field 2 into field "Font2"
   unlock screen
end mouseUp
---------------------------------

then align via your script
Your layout can start "moving"

Additionally not all fonts report proper ascents and descents



Kind regards
Bernd
