*	Always return ImageShader, even from SkShader::MakeBitmapShader	reed	2016-08-02
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Lessons learned 1. ImageShader (correctly) always compresses (typically via PNG) during serialization. This has the surprise results of - if the image was marked opaque, but has some non-opaque pixels (i.e. bug in blitter or caller), then compressing may "fix" those pixels, making the deserialized version draw differently. bug filed. - 565 compressess/decompresses to 8888 (at least on Mac), which draws differently (esp. under some filters). bug filed. 2. BitmapShader did not enforce a copy for mutable bitmaps, but ImageShader does (since it creates an Image). Thus the former would see subsequent changes to the pixels after shader creation, while the latter does not, hence the change to the BlitRow test to avoid this modify-after-create pattern. I sure hope this prev. behavior was a bug/undefined-behavior, since this CL changes that.

*	implement isABitmap for imageshader, return localmatrix for bitmap's impl	reed	2016-08-01
	For imageshader, I only return true if the image is explicitly raster-backed. I do not return true for texture, nor for generator (i.e. lazy/picture) backed. Is that ok?
