cairo: Draw table titles in xr_rendering_draw() too.

xr_rendering_draw() didn't draw table titles.  It seems that this was just
an oversight, so this commit fixes the problem.

xr_rendering_draw() is used by the GUI output viewer window, so this makes
the GUI output viewer display table titles now.

Bug #30554.
