Fix bug #7398 with truncated glyphs in w32 tooltips.
w32fns.c (Fx_show_tip): Call try_window with last argument TRY_WINDOW_IGNORE_FONTS_CHANGE. Delete the TODO ifdef: problem solved. Round up the tip height to an integral multiple of the frame's line height. Add FRAME_COLUMN_WIDTH to the tip width.
