What is left of the SkView system is used only by samples or viewer.
As a result, move it out of the Skia source tree and re-organize so it
is a bit easier to understand and use more shared code.
Move samplecode/ClockFaceView.cpp to samplecode/SampleTextEffects.cpp,
sice that's what's actually in it.
Move SkAnimTimer.h to tools/timer, since it's actually shared between gm
and samples.

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.

This also:
makes the SkLightingShader handle normal maps where the rects aren't aligned between the diffuse and normal maps.
adds a light aggregating class (Lights) to SkLightingShader (along with a Builder nested class).
Split out of https://codereview.chromium.org/1261433009/ (Add SkCanvas::drawLitAtlas call)

Additionally this CL:
forces the light colors to be opaque
forces the light direction to be normalized
adds a raster implementation
adds a gm
