––––– PF_SampleEdgeBehav –––––
The sampling routines always deal with 32 bit images, and thus need to compute properly alpha-weighted samples. An issue arises when an attempt is made to sample outside of the image content area.
Before PF_PLUG_IN_VERSION 2, After Effects always treated pixels outside of the image content area as having alpha = 0, which is desirable in many cases. Distortions and other effects may want different sampling behaviors, however, hence the PF_SampleEdgeBehav.
