Note the / PANGO_SCALE a little further down; Pango units are fixed
Independent of sub-pixel positioning, there will be some quantization
problems if people try to do layout in coordinate systems that are
massively far from 1 unit per point or 1 unit per pixel and need to use
tiny point sizes. But I don't see this as being normal, and if necessary
people can always cairo_scale() before drawing text.
(There is a bit of a convenience problem from the / PANGO_SCALE; it's
possible that pango_layout_size_float() or similar convenience functions
might be useful.)
