[devel]  Use fast integer PNG_DIVIDE_BY_255() or PNG_DIVIDE_BY_65535()

to accomplish alpha premultiplication when PNG_READ_COMPOSITE_NODIV_SUPPORTED
is defined.  Changed "/255" to "/255.0" in background calculations to make it
clear that the 255 is used as a double (and to prevent anyone from being
tempted to use PNG_DIVIDE_BY_255() there).
