Why this change? While there's currently no implementation of
RenderBlockFlow::paint(), I think it's good practice to call the super class
unless there are explicit reasons to avoid it.

I want it to be explicit, so that I can more easily get this whole code out of
here once everything is in the core/paint/ directory.

But a table cell IS a RenderBlockFlow, and it may contain things like floats and
lines.

I don't care that much, so reverted this change.
