Subject: Make sure there code point ranges are in order
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;ds=sidebyside;h=329e747da6ee89d4ed2de15ceacf68b932e56e80;hp=329e747da6ee89d4ed2de15ceacf68b932e56e80;p=ttf2png.git

Make sure there code point ranges are in order

And that there are no overlapping ranges.  The grid rendering logic
depends on being able to determine the total range of code points from
the first and last converted glyph.
