/*
* Windows GUI.
*
* GUI support for Microsoft Windows. Win32 initially; maybe Win16 later
*
* George V. Reilly <george@reilly.org> wrote the original Win32 GUI.
* Robert Webb reworked it to use the existing GUI stuff and added menu,
* scrollbars, etc.
*
* Note: Clipboard stuff, for cutting and pasting text to other windows, is in
* os_win32.c. (It can also be done from the terminal version).
*
* TODO: Some of the function signatures ought to be updated for Win64;
* e.g., replace LONG with LONG_PTR, etc.
