[webkit-dev] Handling Ignorable Text in a Renderer

[Alex Milowski]

In certain MathML constructs (e.g. mfenced) there are a number of child
elements that make up the construct and need to be rendered.  Any text
between those child elements should be ignored.  In fact, non-whitespace
text in the wrong place is most certainly incorrect but something
that can be recovered from.

I don't want to remove the text from the DOM nodes but I need to
keep the RenderText instances from being created or displayed.  What
is the correct way to do this?

I've been trying to handle this in the renderer but it seems like that
is really too late.  I though about changing the attach method to exclude
such ignorable text.
