 If you want the 1/r form you can take the expressions for anisotropic
 gaussian integrals and take the planar limit, but I am not sure that
 you will end up with a closed expression, there might be one integral
 that you have to approximate. The log r integrals can be easily
 computed by a 2d fft.
