Changeset 25313 for trunk/ppStack/src/ppStackMatch.c

Message:

Nigel Metcalfe points out that we shouldn't use extended sources as stamps when convolving to a target PSF. To avoid this, I'm throwing out extended sources when I create the fake image. This requires an API change to pmReadoutFake(). I think I've caught all instances that use that.
