Rename Point and End slices to Points and Ends.

The slice Foos is plural; it refers to multiple elements. The element Foos[i]
is the i'th Foo.

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.

Quantize sub-pixel glyph rendering.
...
This is in anticipation of caching glyph images. Quantization means that cache
hits are more likely.
Also make NewFace take an *Options instead of an Options.

Add a truetype.Face type.

Its implementation is mostly a copy/paste of the freetype.Context type.
Follow-up commits will make it more efficient.
Also add an example that uses a truetype.Face and the
golang.org/x/exp/shiny/font package to draw text.
