32	psImageReadSection and/or psImage has no concept of a mask.	robert.desonia@…	Paul Price	"psImageReadSection has no concept of a mask to mark nul pixels.  Shall I assume
the use of a magic pixel value is to be used?  I thought it was a desire to use
a byte-sized mask array for this purpose instead. 

It may make sense, actually, to add the pixel mask to the psImage struct
instead, as it is highly coupled to the image.
