* VIM - Vi IMproved by Bram Moolenaar
*
* Do ":help uganda" in Vim to read copying and usage conditions.
* Do ":help credits" in Vim to see a list of people who contributed.
* See README.txt for an overview of the Vim source code.
*/
/*
* os_win32.c
*
* Used for both the console version and the Win32 GUI. A lot of code is for
* the console version only, so there is a lot of "#ifndef FEAT_GUI_W32".
*
* Win32 (Windows NT and Windows 95) system-dependent routines.
* Portions lifted from the Win32 SDK samples, the MSDOS-dependent code,
* NetHack 3.1.3, GNU Emacs 19.30, and Vile 5.5.
*
* George V. Reilly <george@reilly.org> wrote most of this.
* Roger Knobbe <rogerk@wonderware.com> did the initial port of Vim 3.0.

/*
* Decode a MOUSE_EVENT. If it's a valid event, return MOUSE_LEFT,
* MOUSE_MIDDLE, or MOUSE_RIGHT for a click; MOUSE_DRAG for a mouse
* move with a button held down; and MOUSE_RELEASE after a MOUSE_DRAG
* or a MOUSE_LEFT, _MIDDLE, or _RIGHT. We encode the button type,
* the number of clicks, and the Shift/Ctrl/Alt modifiers in g_nMouseClick,
* and we return the mouse position in g_xMouse and g_yMouse.
*
* Every MOUSE_LEFT, _MIDDLE, or _RIGHT will be followed by zero or more
* MOUSE_DRAGs and one MOUSE_RELEASE. MOUSE_RELEASE will be followed only
* by MOUSE_LEFT, _MIDDLE, or _RIGHT.
*
* For multiple clicks, we send, say, MOUSE_LEFT/1 click, MOUSE_RELEASE,
* MOUSE_LEFT/2 clicks, MOUSE_RELEASE, MOUSE_LEFT/3 clicks, MOUSE_RELEASE, ....
*
* Windows will send us MOUSE_MOVED notifications whenever the mouse
* moves, even if it stays within the same character cell. We ignore
* all MOUSE_MOVED messages if the position hasn't really changed, and
* we ignore all MOUSE_MOVED messages where no button is held down (i.e.,
* we're only interested in MOUSE_DRAG).
*
* All of this is complicated by the code that fakes MOUSE_MIDDLE on
* 2-button mouses by pressing the left & right buttons simultaneously.
* In practice, it's almost impossible to click both at the same time,
* so we need to delay a little. Also, we tend not to get MOUSE_RELEASE
* in such cases, if the user is clicking quickly.

*
* There is another problem, which isn't really a bug but isn't right either:

* "abcdef~1.txt" again. This has been reported on Windows NT 4.0 with
