Benny Siegert	324e6dabf0	go.image/tiff: optimize reading uncompressed files from a tiff.buffer. In case the image is read via a tiff.buffer, avoid copying the data strip before decoding it. Remove corresponding TODO. Speeds up reading uncompressed images (which is the common case) and uses much less memory. benchmark old ns/op new ns/op delta BenchmarkDecodeCompressed 4619438 4630774 +0.25% BenchmarkDecodeUncompressed 260809 219875 -15.70% R=nigeltao CC=golang-dev https://golang.org/cl/5683050	2012-02-21 11:25:19 +11:00
