db892dd957 draw: clip scaling to the dst bounds.
This is necessary for the upcoming RGBA dst fast path. The RGBA.Set slow
path will clip automatically. Accessing RGBA.Pix directly will not.

a1da419f1a go.image/tiff: fix (TIFF-specific) LZW decompression.
The blue-purple-pink.lzwcompressed.tiff image was created by
"bmp2tiff -c lzw".

2bda575717 go.image/tiff/lzw: fork the standard library's compress/lzw package.
This CL has no code changes. Future CLs will modify the code to
implement TIFF's LZW instead of the standard LZW.

420d421738 go.image/tiff: encoder fix non LZW Predictor and Paletted SamplesPerPixel and non RGB ExtraSamples.
TIFF6.0 Spec:
Page 31: ExtraSamples can only included in RGB mode image.
Page 39, SamplesPerPixel is usually 1 for bilevel, grayscale, and palette-color images.
Page 64, Currently Predictor field is used only with LZW.

Fixes golang/go#6421.

5198c64fc9 tiff: new Options parameter for Encode.
No functional change at the moment but it will allow choosing
the compression type.

This is an incompatible, user-visible change. To get the old
behavior, callers of tiff.Encode need to add ", nil" as the
last parameter.

c35a1ecb6c go.image/tiff: use optimized routines for RGBA and NRGBA
Performance for an RGBA image:

benchmark          old ns/op    new ns/op    delta
BenchmarkEncode      1633495         7897  -99.52%

benchmark           old MB/s     new MB/s  speedup
BenchmarkEncode        37.83      7824.96  206.85x

NRGBA images are now encoded as such, the spec calls it
"unassociated alpha".
