Font::TTF::Delta - Opentype Device tables
Each device table corresponds to a set of deltas for a particular point over a range of ppem values.
The first ppem value in the range
The last ppem value in the range
This is an array of deltas corresponding to each ppem in the range between first and last inclusive.
This is the fmt used (log2 of number bits per value) when the device table was read. It is recalculated on output.
