Nigel Tao 3490800cec freetype/truetype: fix rounding for negative numbers to match the C
Freetype implementation.

The spec is the "Order of rounding operations" part of
https://developer.apple.com/fonts/TTRefMan/RM02/Chap2.html#rounding
but it wasn't exactly clear to me what "the negative round value
closest to zero" was: if the phase is 1/4, was that value -1/4 or
-3/4? Anyway, the Go code now follows the C code, and code trumps
documentation.

This is a port of the Freetype font rasterizer (www.freetype.org) to the Go
programming language (golang.org).

To download and install from source:
$ go get code.google.com/p/freetype-go/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 24.8 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.

Freetype-Go is derived from Freetype, which is written in C. Freetype is
