Increase size of small image components in hints field

[kintopp]

It would be nice if we could make some hand-drawn components bigger and easier to read. Kanji IDs with small components: 30, 45, 47, 53, 54, 55, 56, 57, 60, 64, 71, 74, 75, 76, 78, 80, 84, 85, 87, 89, 96, 97, 98, 100, 104, 116, 123, 124, 127, 129, 131, 133, 136, 140, 144, 146, 150, 151, 161, 165, 166, 178, 183. Not sure if this will involve editing the SVG file or the CSS.
