Fix blocky artifacts in area aa

The numerical robustness work for multisampled aa was not carried over to the area version. This patch changes the computation of y_edge in the tiling stage so that rendering using area antialiasing in fine will match the multisampled case. See the linked bug for a diagram which explains the cases.

Fixes #393
