* GUI support by Robert Webb

/*
* Windows GUI.
*
* GUI support for Microsoft Windows, aka Win32. Also for Win64.
*
* 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
* winclip.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.

*
* Trying to use as more Windows services as possible, and as less

*
* 1) Don't create ToolTip in gui_mch_create_beval_area, only initialize
* BalloonEval struct.
* 2) Enable/Disable simply create/kill BalloonEval Timer
* 3) When there was enough inactivity, timer procedure posts
* async request to debugger
* 4) gui_mch_post_balloon (invoked from netbeans.c) creates tooltip control
* and performs some actions to show it ASAP
