Log Message:
-----------
[regression] feGaussianBlur in filter is not applied if the stdDeviation
contains a 0 in the pair

Reviewed by Dan Glastonbury.
Fix a regression introduced by https://webkit.org/b/315118
FloatSize::isEmpty() is width <= 0 || height <= 0 (FloatSize.h:73),
so stdDeviation="0 5" and "5 0" was now bypassing the blur entirely.
Re-introducing the check on width and height and adding a WPT test case
to catch the regression next time.
