first time I uploaded a patch using git. Bet it won't apply.

[Evan Martin]

Needs a test or a discussion of why it can't be tested in the changelog.  :\

What Mr Martin said. Other than that it looks fine.

[Evan Stade]

ok, I found a repro. Go to a page with an SVG, and then hit shift-f5 and drag like mad from the point where the SVG is going to load. After several tries it should crash the renderer. Unfortunately it appears my js abilities are too weak to create a test out of this.

Whoa, we can do unit tests in webkit?

Probably want s/m_NativeImage/m_nativeImage/g.

The code looks good to me, but I am not a reviewer.

Yes, the unit tests are a new development I believe. (git log says Jan 8 -- not that new apparently)

I believe that the header style error is not applicable for unit tests.

Two nits: m_size (instead of m_Size) and put the comma before the m_size instead of on the previous line.

That's all though.

Didn't mark cq+ yet... as it would be nice to wait for the chromium ews to turn green.

Changing back to r? to allow ews to pick it up.
