582	psImageTransform	robert.desonia@…	Paul Price	"In the latest SDRS, the blankPixels argument is now a psArray**, but it is not clear why.  Frankly, I don't 
know why it can not just be a psPixels*.

Can you expand on the description of this function so that it is absolutely clear what blankPixels should 
return.  Is it a list of pixel locations in the output image that do not correspond to a pixel in the input 
image?

Also, was it changed to a double-pointer from single-pointer because you wanted the function to 
allocate the appropriate psArray or psPixels (depending on the outcome of the last question)?  Right 
now, it assumes that if you pass a NULL, you don't want  this information returned, which seems handy.  
It does, however, put the responsibility on the user to allocate the output object prior to invokation.
