ReadRoberts 8b02b5a294 Fixed issue with reading/writing PrivateDict BlueValues to ttx file. To date, BlueValue arguments have been written as absolute coordinate values, reflecting the history of the CFF ttx table format. However, Behdad Esfahbod pointed out that it is not always possible to roundtrip between the absolute values in the ttx file and the CFF2 default font value and the delta list. This update changes the ttx format so that in PrivateDict BlueValues, the default font values are written as absolute coordinates, preserving continuity with how CFF tables are written, but the region values are written as the deltas from the VariationStore delta list.

This also fixes fonttools/fonttools/issues/1030.

Although the roundtrip is generally possible when a VariationStore is built from source font data using the Superpolator model, it is possible to  build  region definitions that do not follow this model. Behdad cited the Skia "Q" example, where the tail of the Q is affected by two regions defined as:
min=0 peak=0.5 max=0.51 delta=+10
min=0.49 peak=0.5 max=0.51 delta=-10
