File: PrefsWindow.c
Abstract: Handles all Window and List related functions for the Demo.
Version: 2.0
Change History:
<2.0> Carbonized
for the Carbon version we're using CreateCustomList to
create the list
introduced some new globals to account for the different
theme metrics between the Platinum and Aqua appearances
<1.0> first release version
this draws a list directly into a window and mimics the
behavior of a list box control
it turns out this was actually quite difficult, there is
a LOT of background color/pattern changing you have to
do to achieve the desired effect
