In `display/canvas.js` the accent offsets must be multiplied by `fontSize` to make the offsets large enough. Another problem is in `core/type1_parser.js` when the Type1 command `seac` is handled. There is an error in the Adobe Type1 spec. See chapter 6 in Type1 Font Format Supplement, which provides an errata: The arguments of `seac` specify the offset of the left side bearing (LSB) points, not the offset of origins. This can be fixed in `core/type1_parser.js` by adding the difference of the LSB values.
