I am looking for a class-library that will help me integrate line drawing 
capabilities into a C++ application that I am building with Borland C++.

I am using (and really like!) the OWL (Object Windows Library) class library
from Borland, and if it exists the ideal software would have the following 
characteristics:

  -  Fully integrated with OWL, i.e. written in C++, objects would be subclassed
     from Object, or WindowsObject OWL classes
  -  Provide line-drawing capabilities a-la MacDraw (squares, lines, 
     polygons, fills, arrows, linestyles, grouping, moving, resizing...
  -  Allow objects to be interrogated for their sub-objects, i.e. a square
     consists of 4 lines, and I need to iterate over the lines.
  -  Have a one-time charge for development use, with no run-time royalties
     or restrictions.
  -  Cost less than $100  :)

My research so far has uncovered a couple of textbooks (one by Peter Norton and 
Paul Yao) which provide sketches of such a solution, and rather than 
re-inventing I would prefer to re-use (!) somebody elses solution.

I will summarize to this group.

Thanks in advance.
