[scaled-font] Use full ctm matrix when comparing scaled-font keys

Browse source 
We use the full matrix in hash computation, but only compare the
non-translation items in equality check.  This is no bug though,
as we set the ctm translation components of a scaled font to zero
explicitly.  But the change makes the hash and equal functions
consistent, which is good.
