[cups.general] Canon UFR-II drivers

[Michael Sweet]

As the CUPS libraries are LGPL2, they are permitted to distribute binary-only drivers.

However, if the vendor is supplying source under the GPL with a required binary module that is not part of the OS, that actually *does* violate the license they have chosen for their drivers, however they can also include an exception in their copy of the GPL (like we do for certain things in CUPS) to specifically allow it for their driver.
