Change SkTime::GetMSecs to double; ensure values stored in SkMSec do not overflow.
The following are currently unused in Android, Google3, Chromium, and Mozilla:
- SkEvent
- SkTime::GetMSecs
- SK_TIME_FACTOR (also unused in Skia)
- SkAutoTime
I left uses of SkMSec more-or-less intact for SkEvent, SkAnimator, and SkInterpolator. SkInterpolator is used in Chromium, so I did not want to change the API. The views/ and animator/ code is crufty, so it didn't seem worthwhile to refactor it. Instead, I added SkEvent::GetMSecsSinceStartup, which is likely to be adequate for use in SampleApp.
I also left SkMSec where it is used to measure a duration rather than a timestamp. With the exception of SkMovie, which is used in Android, all of the uses appear to measure the execution time of a piece of code, which I would hope does not exceed 2^31 milliseconds.
Added skiatest::Timer to support a common idiom in tests where we want to measure the wallclock time in integer milliseconds. (Not used in tests/PathOpsSkpClipTest.cpp because it redefines things in Test.h.)
Removed tabs in tests/StrokerTest.cpp.
