This weekly snapshot includes changes to the io, image, and math packages that
may require changes to client code.
The io package's Copyn function has been renamed to CopyN.
The math package's Fabs, Fdim, Fmax, Fmin and Fmod functions
have been renamed to Abs, Dim, Max, Min, and Mod.
Parts of the image package have been moved to the new image/color 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,
at a later date.
