Originally by Ray Chason for 3.4.3, based on the Qt windowport by
Warwick Allison. The look and feel is mostly the same.
Some improvements over the Qt 3 interface are:
* Panes are resizable
* Full support for IBMgraphics, and walls and corridors are drawn with
graphical primitives for a continuous appearance no matter what the font
says
* Lots of irritating glitches fixed
* Menus support proportional fonts correctly
Adding this because the old Qt windowport cannot be compiled on Qt4,
even with Qt3 compatibility stuff.

- background map glyphs
- status hilites
- menucolors
