Detailed Description

The FontFamilySizeInfo class Some font-families have different designs for different sizes. These are largely differences in weight, spacing and small glyph changes. There's four places opentype stores the design size information:

Different bitmap strikes in the font file. Bitmap fonts do the same.
The OS2 table entry.
The 'size' opentype feature.
The 'opsz' axes in either variable fonts or the stat table.

Of these, 1 and 4 are supported properly, but we need to keep track of 2 and 3 as well, to ensure that these fonts are still selectable in the font picker.
