- /*
- * A `CF2_Blues' object stores the blue zones (horizontal alignment
- * zones) of a font. These are specified in the CFF private dictionary
- * by `BlueValues', `OtherBlues', `FamilyBlues', and `FamilyOtherBlues'.
- * Each zone is defined by a top and bottom edge in character space.
- * Further, each zone is either a top zone or a bottom zone, as recorded
- * by `bottomZone'.
- *
- * The maximum number of `BlueValues' and `FamilyBlues' is 7 each.
- * However, these are combined to produce a total of 7 zones.
- * Similarly, the maximum number of `OtherBlues' and `FamilyOtherBlues'
- * is 5 and these are combined to produce an additional 5 zones.
- *
- * Blue zones are used to `capture' hints and force them to a common
- * alignment point. This alignment is recorded in device space in
- * `dsFlatEdge'. Except for this value, a `CF2_Blues' object could be
- * constructed independently of scaling. Construction may occur once
- * the matrix is known. Other features implemented in the Capture
- * method are overshoot suppression, overshoot enforcement, and Blue
- * Boost.
- *
- * Capture is determined by `BlueValues' and `OtherBlues', but the
- * alignment point may be adjusted to the scaled flat edge of
- * `FamilyBlues' or `FamilyOtherBlues'. No alignment is done to the
- * curved edge of a zone.
