Comment(by dustymugs):

 Assuming that mixed array is what's being passed at the SQL level, you
 can't do that. PostgreSQL arrays must have all elements of one datatype.
 The programmatic padding is also undesirable.

 I was thinking that the use of distancex and distancey would only be
 present at the SQL level. Everything passed to the C side (rtpg_ and rt_)
 and within the C side would only be of a mask object.
