bcfeb16b74 Allow multiple kern subtables. 
We still only use the first subtable, but we no longer fail if there's
more than one subtable.

b12e981082 Support Unicode Full Repertoire cmap tables. 
For example, "Apple Color Emoji.ttc" has such a cmap. After this commit,
we can render its glyph for "U+0001F1E6 REGIONAL INDICATOR SYMBOL LETTER
A", which is clearly outside the Unicode BMP.

Note that this only lets us render black-and-white glyphs for out-of-BMP
runes. Rendering color glyphs (i.e. emoji) remains TODO.

3cc748686b Use fixed.Rectangle26_6 instead of truetype.Bounds. 
The previous "the endpoints are inclusive" comment seems confusing. It's true
that the bounding box's max X equals the right-most coordinate, which suggests
<= instead of <, but that node's coordinate is itself exclusive. Consider the
solid 1-pixel square: (0, 0), (64, 0), (64, 64), (0, 64) in fixed.Point26_6
coordinates. The right-most coordinate is 64, and the bounding box's max X
equals 64, but rasterizing that square only affects sub-pixels up to but not
including 64.

Instead, it seems accurate to follow the fixed.Rectangle26_6 description, in
that the max values are exclusive.
