For reference if anyone is curious, any pixel size that is not a
multiple of 5 will exhibit the problem.  A couple common ones are 72px
and 96px which should be a 72x72 and 96x96 respectively.  Leading is 0
for Ahem so height should be ascent+descent.

Ascender: 3712 Descender: -960 >> Height: 4672 == 73px
Ascender: 3712 Descender: -896 >> Height: 4608 == 72px

Ascender: 4928 Descender: -1280 >> Height: 6208 == 97px
Ascender: 4928 Descender: -1216 >> Height: 6144 == 96px
