* resolution to a value R' > R, the page size in pixels will get multiplied

* limitcheck. That is why the bbox device must set the resolution to a
* value larger than that of any real device. A consequence of this is that
* the page size in inches is limited to the maximum representable pixel
* size divided by R, which gives a limit of about 120" in each dimension.
