[Inc. Repainting] Fix for nil dereference

[David Hyatt]

I'm going to use "[Inc. Repainting]" in the subject line to talk about 
any patches related to the experimental repainting code I landed.

This patch fixes a nil dereference caused by my change to make 
m_needsLayout be false initially instead of true.
