Sorry, been busy
As you've figured out, text margins work as a pixel offset from the bounding box (in most cases the image behind the text). As it says in the
sdk:
For *.margin, the first four coordinates represent left, top, right, bottom margins, respectively, and the fifth coordinate represents (when supported) where to justify text (0=left,0.5=center,1=right)
trans.margin does the same, but with
everything in the transport. You might find it of use in an undocked transport bar, but I didn't bother with it.
Alas, and yes, you can't set min/max height/width for many of the panels where it would be super useful ...its early days.
