507	Region conventions	Paul Price	Paul Price	"psLib is adopting the C convention that the first pixel is 0,0.  The FITS
standard says it should be 1,1.  Image regions in the header (e.g., DATASEC) are
generally written following the FITS standard, e.g., [1:2048,1:4096].  Does this
mean that psRegionFromString/psRegionToString must convert to/from psLib
convention, or do we introduce a new function to perform the conversion?  We
also need to be careful about whether functions treat regions as inclusive or
exclusive of the boundary (esp. the upper limit)."	defect	closed	high		PSLib SDRS	unspecified	normal	fixed
