Hallo Helmut,

i wonder - now that we trace glyph matrices, could we get rid of the
ambig roots created in dispnew.c? like

#ifdef HAVE_MPS
                igc_xnrealloc_ambig (row->glyphs[LEFT_MARGIN_AREA],
                               dim.width, sizeof (struct glyph));
#else
                xnrealloc (row->glyphs[LEFT_MARGIN_AREA],
                           dim.width, sizeof (struct glyph));
#endif
