Changeset 19383 for trunk/psLib/src/fits/psFitsScale.h

Message:

Adding capability for a mask to be provided when determining BSCALE,BZERO. This is required for the case when a large masked region of the image has been set to a constant (or close to a constant). If the mask is not provided in this case, then the standard deviation is under-estimated, leading to a choice of BSCALE,BZERO that adversely affects the dynamic range of the image. Added functions psFitsWriteImageWithMask, psFitsUpdateImageWithMask and psFitsInsertImageWithMask, and kept the APIs of psFitsWriteImage, psFitsUpdateImage and psFitsInsertImage so that this change shouldn't break anything.
