You can use ‘window-text-pixel-size’ for this but I don't understand
what you need it for.  The basic slider size and position calculations
are done in set_horizontal_scroll_bar in xdisp.c and that function calls
the set_horizontal_scroll_bar_hook corresponding to your platform which
should be ns_set_horizontal_scroll_bar.  The latter probably needs some
tweaking as for the other platforms.
