The %PANGO_SCALE macro represents the scale between dimensions used
for Pango distances and device units. (The definition of device
units is dependent on the output device; it will typically be pixels
for a screen, and points for a printer.) %PANGO_SCALE is currently
1024, but this may be changed in the future.
When setting font sizes, device units are always considered to be
points (as in "12 point font"), rather than pixels.
