The previous PEGs on coordinate systems were a tad unclear
on the overall goals - hopefully these new methods will
clarify the picture.
For example, a box coordinate system and an aspect ratio
coordinate system (a mapping from (0,w)x(0,1) to (0,1),(0,1))
we can define a padded text coordinate system (i.e. one which
has isotropic coordinates relative to the parent coordinate system)
based only on these two coordinate systems::
def paddedText(box, aspectratio):
vs.
