Major bugs related to the metric information in the font
output were fixed. Min, max, ascent, and descent are now
calculated correctly, and the hdmx (horizontal device
metrics) table is no longer misused. There was another
bugfix related to UI initialization, which was causing JVM to
hang occasionally on startup. New features, including
rounding support, interpolation emulation, preview of glyph
using the built font, and search text field, were added.
