Fork of golang/freetype with some extra stuff

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. |

The Freetype font rasterizer in the Go programming language.
To download and install from source:
$ go get github.com/golang/freetype
It is an incomplete port:
* It only supports TrueType fonts, and not Type 1 fonts nor bitmap fonts.
* It only supports the Unicode encoding.
There are also some implementation differences:
* It uses a 26.6 fixed point co-ordinate system everywhere internally,
as opposed to the original Freetype's mix of 26.6 (or 10.6 for 16-bit
systems) in some places, and 24.8 in the "smooth" rasterizer.
