#42 Scrolling Exhibits Coordinate-Space Confusion

Build Macintosh Carbon Quesa shared libraries. Retrieve <a
href="http://www.halcyon.com/www3/jesjones/Whisper/
Home.html">Whisper 2</a> from CVS to get Carbonized version.
Also check out "Extras" module. Build Hypermandella in "Extras"
folder. Place "Quesa" shared library in Hypermandella folder.
Launch Hypermandella. Allow rendering of fractal to complete.
Shrink window until scroll bars appear. Scroll around.

By appearances, Quesa is getting confused (still) as to what the
origin of its drawing context is. If memory serves me correctly,
this bug is long-standing and has been believed to have been fixed
before.
