/*
 * 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.

 * to get current mouse position).
 *
 * Trying to use as more Windows services as possible, and as less
 * IE version as possible :)).
 *
 * 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
 * 5) WM_NOTIFY:TTN_POP destroys created tooltip
