R devel - Jul 1997 - R-alpha: R 0.50.a1: small patches for graphics and image demo

Applying the following patches closes the following task (part 1 was
already taken care of).

TASK:   New Problems
STATUS: Open
FROM:   <Kurt.Hornik@ci.tuwien.ac.at>
        New minor remarks:
        * The documentation for `image' still has the old order z, x, y.
        * Perhaps one should add `par(ask = T)' in the image demo?
        * Perhaps one should save the original value of par() at the
	beginning of the graphics demo, and restore that at its end
	(s.t. typically asking is turned off again).

Thanks,
-k
