This patch adds a new base render object for inline-block elements of MathML.  It also sets up the necessary bits for all the rendering objects to follow.

RenderMathMLBlock Patch

In RenderMathMLBlock::styleDidChange, why are you marking the block as needing layout and pref width recalc always?  That's really inefficient. I'm also not clear on wny it's necessary.  Isn't the style diff doing the right thing in the base classes?

In isChildAllowed you don't have to do ? true : false.  Just return the conditional itself.

stretchToHeight would be cleaner using a for loop to walk the children in my opinion.

for (RenderObject* current = firstChild(); current; current = current->nextSibling());

It seems like makeBlockStyle should return a PassRefPtr, since you're wanting to have it be set on some RenderObject presumably.

The styleDidChange method was removed.  It isn't necessary in the code.

The other changes have been made.
