27	psImageFreePixels needed?	robert.desonia@…	eugene	"I noticed that there is no function to (re)allocate pixel data for a psImage,
but there is a free function, psImageFreePixels.

Is this a mistake?  Do you need a freePixels function if you don't have a
allocPixels function? Is it that you envision creating a number of children
images then freeing the parent image's pixel data to save memory?

Also, if one calls psImageFreePixels on a psImage, is numCols/numRows set to
zero?  If not, do we need a function to determine if a psImage has a valid pixel
buffer allocated?"	defect	closed	high		PSLib SDRS	unspecified	normal	fixed
