10498f4d33 image: remove image/bmp and image/tiff from std.
They have moved to the code.google.com/p/go.image subrepo.

a2846e65dc image: spin off a new color package out of the image package.
The spin-off renames some types. The new names are simply better:
image.Color              -> color.Color
image.ColorModel         -> color.Model
image.ColorModelFunc     -> color.ModelFunc
image.PalettedColorModel -> color.Palette
image.RGBAColor          -> color.RGBA
image.RGBAColorModel     -> color.RGBAModel
image.RGBA64Color        -> color.RGBA64
image.RGBA64ColorModel   -> color.RGBA64Model
(similarly for NRGBAColor, GrayColorModel, etc)

The image.ColorImage type stays in the image package, but is renamed:
image.ColorImage -> image.Uniform

The image.Image implementations (image.RGBA, image.RGBA64, image.NRGBA,
image.Alpha, etc) do not change their name, and gain a nice symmetry:
an image.RGBA is an image of color.RGBA, etc.

The image.Black, image.Opaque uniform images remain unchanged (although
their type is renamed from image.ColorImage to image.Uniform). The
corresponding color types (color.Black, color.Opaque, etc) are new.

Nothing in the image/ycbcr is renamed yet. The ycbcr.YCbCrColor and
ycbcr.YCbCrImage types will eventually migrate to color.YCbCr and
image.YCbCr, but that will be a separate CL.

Also add grayscale test cases for image/decode_test.

0d111a62e1 image/jpeg: decode grayscale images, not just color images.
Also add an image package test that DecodeConfig returns the same
ColorModel as what Decode would.

92834d351e image/gif: GIF decoder
It's incomplete but sufficient to decode 8-bit GIFs without interlacing
or transparency.   More to come.

I'll put in more tests as the feature set grows.

d97b8a817b image/tiff: implement a decoder.
The current iteration can decode 8-bit images in
grayscale, paletted, RGB, RGBA and NRGBA mode. LZW compression
is implemented but does not work on my test images.
Deflate (i.e. zlib) compression with or without a horizontal
predictor is supported.

8a90fd3c72 os: New Open API.
We replace the current Open with:
OpenFile(name, flag, perm) // same as old Open
Open(name) // same as old Open(name, O_RDONLY, 0)
Create(name) // same as old Open(name, O_RDWR|O_TRUNC|O_CREAT, 0666)

This CL includes a gofix module and full code updates: all.bash passes.
(There may be a few comments I missed.)

The interesting packages are:
        gofix
        os
Everything else is automatically generated except for hand tweaks to:
        src/pkg/io/ioutil/ioutil.go
        src/pkg/io/ioutil/tempfile.go
        src/pkg/crypto/tls/generate_cert.go

7483c6ee3c image: add a decoding test for common file formats.
The test image was converted from doc/video-001.png using the
convert command line tool (ImageMagick 6.5.7-8) at -quality 100.
