/************************************************************************
|
||
|
|
|
||
|
|
Minimalist GUI framework built using MFC.
|
||
|
|
|
||
|
|
This package mimics the baseline GUI framework originally implemented
|
||
|
|
on top of FLTK in <gui.h>. It remains incomplete, and does not
|
||
|
|
support all the features provided by the FLTK-based version.
|
||
|
|
|
||
|
|
At this point, the two GUI implementations are close to
|
||
|
|
source-compatible, but not quite. The main difference is in the
|
||
|
|
startup issues -- main() vs. InitInstance().
