* 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)
