Attempt a fix for the overlap removal problems by adding functionality for consolidating duplicate and near-duplicate intersections.
Fix a few bad accesses in the new spline overlap code.
Fix mlist t-value mismatch for adjacent segments.
Allow for an easy reduction in verbosity.
Fix parsing of CFF format 1 encoding
Parsing of CFF files would shift the encoding by one when the CFF file used
encoding format 1. The first code point would incorrectly point to .notdef, then
subsequent encodings would be shifted by 1.

Fix is to correctly skip the .notdef glyph when parsing encoding. CFF format
implies that glyph_id 0 is .notdef, so all encodings start with glyph_id 1.
Format 0 handled this correctly, but format 1 was starting with 0 instead of 1.

Fix parsing of CFF format 1 encoding
Fix range boundary when parsing encoding for CFF font with custom encoding 1

from CFF format specification, format 1 has the following makeup:
card8: first character in range
card8: number of additional characters (excluding the first)

This change corrects the calculation of the code of the last character in range
to respect the fact that the additional character specification excludes the
first character in the range.
Try returning 0 to the default event handler in order to get tabbing working in the metrics view.
Disable verbose spline overlap output in preparation for merging.
Add key-up support for tabbing in the metrics view.
