Rules inside imports should use the fast selector checker codepath.

That they don't is just a bug that crept in at some point.

Explicitly flush the underlying SkDeferredCanvas for HW accelerated 2D canvas when drawImage from WebGL.

When drawing a TextureBacked SkBitmap, it should draw immediately instead of deferring it for later batch draw to avoid
the situation that the TextureBacked SkBitmap is changed before the actual draw and the change is refelected to the
Canvas as well.

Get rid of last uses of deprecated toWebCoreString(v8::Handle<v8::Value>)

Get rid of last uses of deprecated toWebCoreString(v8::Handle<v8::Value>). Calls
have either been replaced by the new toWebCoreString(v8::String) or by the
V8TRYCATCH_FOR_V8STRINGRESOURCE*() macros in cases where it can throw an
exception.

Web Animations CSS: Dont decompose when interpolating with the empty transform list

r162457 [1] attempted to force transform animations to be animated on the
comositor (as in the legacy engine) by substituting an empty transform list
with the identity matrix. This had the side effect of forcing interpolation
with an empty list down the matrix decomposition path resulting in
interpolation errors.

This patch avoids these problems by converting only the output of transform
interpolation from the empty transform list to the identity matrix.
