If you include a half inch margin on every edge (not unreasonable)
your US paper becomes 10/7.5 which is 4/3!

Either of these would be acceptable.

This is not WYSIWYG, however. Unless you mean that IDL knows the paper
in the printer will be A4 and gives a graphics window with an appropriate
aspect ratio "automatically".

The important thing to note here is that for a WYSIWYG to work IDL must
know something about the printer (I'll argue that it currently knows
nothing about the printer other than emulation) or IDL must impose
standards (like aspect ratio) adhered to by both the Video display and
printer "emulation" software. As is always the case, there are limitations
(particularly in the case of fonts) where some (video/windowing) hard/soft-
ware will not allow for all of the capabilities found in printers (such as
arbitraty rotation of hardware fonts). WYSIWYG works well on Apples/Macs
since THE vendor controlled both the hardware (video and printers) as well
as the software - a definite advantage if not a requirement.

WYSIWYGs are difficult to implement and we are asking for a lot of work
here, but that does not decrease my desire for this "feature" to appear
in a future release.
