C++ side v3

Perhaps logFailure should be [noscript]...

Add example call to LogFailure when binding a buffer fails

"Mapping pixel buffer failed\n" maybe? It will be the fMapBuffer call that is failing.

It might also be useful to log the value of mPixelBufferSize since that seems like the most likely cause of failure for this.

Looks good though, who do we have to bribe to get approval for this bug?

No need for newlines between GetWebGLParameter and others.

Do we need to add "using GfxInfoBase::GetFailures" and "using GfxInfoBase::LogFailure" to all the subclasses?

Put the nsCString first for optimal packing

Blame Ehsan more by putting his email address in

FWIW, this could be written as:

      let trGraphicsFailures = gfxInfo.getFailures().map(
          createParentElement("tr", [
            createElement("td", value)

r=me on either your js-ey version or my pythonic version.

Why do you think the alignment will be > 32 bits?
This landed in the latest nightly as:

One slightly minor cosmetic issue: 
If there are no failures shown, the additional table (<tbody id="graphics-failures-tbody">) shows empty, adding a double border to the bottom of the table above it (<tbody id="graphics-tbody">).
What's left to fix here?
