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.

b5a480f035 image: add image.Tiled type, the Go equivalent of Plan9's repl bit.
Make ColorImage methods' receiver type be a pointer.

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.
