* win/tkWinWm.c: backport of several items from 8.5 head:
(ReadIconFromFile): when using SHGetFileInfo to retrieve icon, get
regular icon as well for correct Alt-Tab icon. (hobbs)
Fix for #742882 "Potential division by zero in gridded wm
geometry" (jenglish)
(UpdateWrapper): Let overrideredirect'ed window's wrapper be the
child of desktop window, thus making it to behave more similarly
to X11 Override Redirect. Esp. useful for combobox-like
megawidgets. (kovalenko)
(InstallColormaps): Check for TK_ALREADY_DEAD to avoid handling of
dead windows. (kovalenko)
Change 'panic' to 'Tcl_Panic' (davygrvy)
