Simon Tatham f9a46a9581 gtkfont: use PANGO_PIXELS_CEIL to work out font metrics. 
Colin reports that on betas of Ubuntu 20.04, Pango has switched to
getting its font metrics from HarfBuzz, and a side effect is
apparently that they're being returned in the full precision of
PANGO_SCALE fixed point.

Previously, Pango appears to have been returning values that were
always a whole number of pixels scaled by PANGO_SCALE. Moreover, it
looks as if it was rounding the font ascent and descent _up_ to a
whole number of pixels, rather than rounding to nearest. But our code
rounds to nearest, which means that now the same font gets allocated
fewer vertical pixels, which can be enough to cut off some ascenders
or descenders.

Pango already provides the macro PANGO_PIXELS_CEIL, so it's easy to
switch over to using it. This should arrange that any text that fits
within the font's stated ascent/descent measurements will also fit in
the character cell.
