Fix most of bug #16051 with redisplay loops when resizing tool-bar.

 src/xdisp.c (tool_bar_height): Use WINDOW_PIXEL_WIDTH to set up the
 iterator X limits, not FRAME_TOTAL_COLS, for consistency with what
 redisplay_tool_bar does.  Improve and fix commentary.
 (hscroll_window_tree): Don't assume w->cursor.vpos is within the
 limits of the glyph matrices.
