skia2/samplecode/SampleAAClip.cpp
Ben Wagner b2c4ea6219 Move Views into Sample and Viewer.
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.
