Based on the script, East Asian width, base gravity, and hint,
returns actual gravity to use in laying out a single character
or PangoItem.
This function is similar to pango_gravity_get_for_script() except
that this function makes a distinction between narrow/half-width and
wide/full-width characters also. Wide/full-width characters always
stand <emph>upright</emph>, that is, they always take the base gravity,
whereas narrow/full-width characters are always rotated in vertical
context.
If base_gravity is PANGO_GRAVITY_AUTO, it is first replaced with the
preferred gravity of script.
