- Added xIsEpochDate option to save redundant encoding to Date objects when X axis is already in units of epoch time (performance improvement for large data sets).
- Using requestAnimationFrame to make animatedZooms smoother.
- Made doUnzoom() and predraw() methods public (to allow more graph control).
- Renamed RGBColor to RGBColorParser to avoid a function name collision with: http://www.w3.org/TR/DOM-Level-2-Style/css.html#CSS-RGBColor
Hackish way of testing against dygraphs-combined. Tacky but it works!
- Changes from code review:
  - Refactored repeatAndCleanup() function.
  - Reverted making private methods doUnzoom and predraw public.
  - Put requestAnimationFrame shim function in Dygraph namespace.
Make new options stuff work with gviz.
Minor whitespace tweak.
Move common code to Util.js, reducing multiple-axes tests.
Centralize utility methods in automated tests.
Whoops, remove labels.js from auto_tests/misc/local.html
Set up the ability to fail tests on warnings.
Remove superfluous warning when specifying labelsKMG2.
Add tests for labelsKMG and labelsKMB2.
- Refactored requestAnimFrame.
- No longer need xIsEpochDate, so removed.
Merge remote-tracking branch 'upstream/master' into rgbcolor_change
Fixed typo.
Add tests that break currently, but will pass when http://code.google.com/p/dygraphs/issues/detail?id=412 is fixed.  (Log scale works again.)
- Minor updates from the code review.
Missed an RGBColor-->RGBColorParser change.
Fix logscale. Also fix includeZero (and add tests for it.) Probably fixes all those special per axis options which should now use the other axis-property specification.
Merge branch 'master' of https://github.com/danvk/dygraphs into unzoom
