In my experience (limited, I admit), resizing a bitmap can have a
negative effect on quality ranging from slight to very great indeed. I
suspect the former comes from an even numeric rescaling (e.g., 80% or
120%), while the latter is the consequence of repeated arbitrary
resizings with the mouse. 

I don't know if resizing/rescaling causes pixels to be added/discarded,
but it sure seems that way. When you specify a dpi setting, the pixels
in the bitmap remain unchanged, only their spacing changes.
