87d9e7e166 image: change Pix[0] to mean top-left corner of an image's Rect instead
of the origin.

image/png and image/jpeg benchmarks show no significant changes.

The image/draw changes suggest to me that making a gofix for this is not
feasible. People are just going to have to make manual fixes.

Avoids a lot of redundant bounds checks.

5eb35e4247 image: replace Width and Height by Bounds, and introduce the Point and
Rect types.

The actual image representation is unchanged. A future change will
replace the {[][]color} with {[]color, stride int, r Rectangle} and
possibly a clip region.

The draw.Color, draw.Point and draw.Rect types will be removed in a
future change. Trying to do it in this one polluted the diff with
trivia.

a3d1045fb7 1) Change default gofmt default settings for
parsing and printing to new syntax.

   Use -oldparser to parse the old syntax,
   use -oldprinter to print the old syntax.

2) Change default gofmt formatting settings
   to use tabs for indentation only and to use
   spaces for alignment. This will make the code
   alignment insensitive to an editor's tabwidth.

   Use -spaces=false to use tabs for alignment.

3) Manually changed src/exp/parser/parser_test.go
   so that it doesn't try to parse the parser's
   source files using the old syntax (they have
   new syntax now).

4) gofmt -w src misc test/bench

3rd set of files.
