Comment(by dustymugs):

 I guessed this, st_wedge and st_annulus were related to doing focal stats.
 I wonder if this is better done as separate functions as currently
 ticketed or something more general.  Essentially, these functions are
 masks.  For my work I have a mapalgebra callback function that supersedes
 itself between mapalgebra and the actual processing callback function
 since I need to clip the neighborhood processed to a circle of some
 radius.
