Patch by Thiago Marcos P. Santos <thiago.santos@intel.com> on 2012-08-15
Reviewed by Kenneth Rohde Christiansen.

Source/WebCore:

Set the default font when no parent style is set. It will make
possible to apply relative units when a parent is not set.

No new tests, unskipped the existing ones.

* css/StyleBuilder.cpp:
(WebCore::ApplyPropertyFontSize::applyValue):
Make it possible to apply relative units if a parent style exist but
not a parent node. It works like this for em and ex, but not for
percent units.
* html/canvas/CanvasRenderingContext2D.cpp:
(WebCore):
(WebCore::CanvasRenderingContext2D::setFont):

LayoutTests:

Unskipped tests that will now pass, removed wrong expectations
and updated test case which was fixed by the W3C.

* canvas/philip/tests/2d.text.font.parse.size.percentage.default.html:
This test case was fixed on W3C upstream:
