[Rd] image adds lines

There seems to be a bug in "image" in R 13.1 (on windows 32 & 64 bits) and on R-devel that is not present in R 13.0 and before.

The below creates a plot with many white lines, horizontal and vertical, more or less regularly spaced. The effect is particularly dramatic when the plotting window is made very small.
