ce0faa1867 font/sfnt: flip the Y axis for LoadGlyph's Segments. 
The underlying font format's Y axis increases up. The Go standard
graphics libraries' Y axis increases down. This change makes the Go API
consistent with the other Go libraries.

Also change Segment.Args from [6]fixed.Int26_6 to [3]fixed.Point26_6 to
emphasize that the Args are consistent with other fixed.Point26_6 use.

ecc1a9abb6 font/sfnt: fix argStack size check for moveto ops. 
The *moveto ops don't take multiple args or arg pairs. For example, in
http://wwwimages.adobe.com/content/dam/Adobe/en/devnet/font/pdfs/5177.Type2.pdf
page 16, the rmoveto args are listed as:
dx1 dy1
which is not the same as rlineto's args, which can be repeated:
{dxa dya}+

This will lessen the diff in a subsequent commit, which introduces a
call stack.
