cc: Remove area calculation overflow in PictureLayerImpl::AppendQuads.

This patch ensures that we don't overflow integer bounds when
calculating area for various reporting. Note that the types in which
the value is stored is already int64_t; it's just a matter of ensuring
the temporary calculation on the rhs also uses 64 bit ints.
