New in mustang is support for kerning and ligatures via attributes on a Font.
These when applied can affect the advance of a string of latin chars which
currently FontDesignMetrics optimises to be the sum of the non-kerned advances
assuming a 1:1 char:glyph mapping. Thus it can return incorrect results in this case.
This doesn't affect any existing code or app as its only in mustang that its possible
to specify this.
