135	psImageTrim need to realloc buffer or not?	robert.desonia@…	Paul Price	"Should psImageSubset be making a shallow subset/trim, while the psImageTrim 
does a hard subset/trim? 
 
If then when psImageTrim is performed, does it resize the image buffer or 
leave it alone (wasting the difference of sizes in memory but saving in time)?  
If we were to add an additional attribute to the struct holding the raw buffer 
location (and maybe size), one could perform a trim (or an psImageSubset?) by 
just resetting the row pointers.  FFT transforms would be required to be 
tweaked (to handle the row stride, an advanced feature in FFTW3), but it looks 
not to be a much of a problem. 
 
What do you think?
