Nigel Tao c20323d2bb image/draw: add a fast path for Gray src images. ... Grayscale PNG and JPEG images are not uncommon. We should have a fast path. Also add a benchmark for the recently added CMYK fast path. benchmark old ns/op new ns/op delta BenchmarkGray 13960348 324152 -97.68% Change-Id: I72b5838c8c3d1f2d0a4536a848e020e80b10c0f7 Reviewed-on: https://go-review.googlesource.com/6237 Reviewed-by: Rob Pike <r@golang.org>		2015-02-28 21:43:39 +00:00
