strange interaction between rasterImage and Grid graphics

Hi,

Thanks for the follow-up.

Dear all,

This may be specific to Mac, I haven't had a chance to test another
platform. Consider this,

plot(1,1,t="n")
rasterImage(matrix(1),1,1,1,1)
library(grid)
grid.rect(gp=gpar(fill="grey"))

The grid.rect covers the full device window as expected. However, when
I resize the window ever so slightly (interactive device) the rectGrob
is suddenly clipped to the previous plot window. I cannot understand
this behavior, and it doesn't happen if one removes the rasterImage()
call, so I suspect something iffy is going on with the display list or
something.
I can reproduce the behaviour on GNU/Linux x11(type="cairo"), but this
is inappropriate mixing of base and grid graphics, so officially I
don't think you are allowed to expect anything at all.

I think the gridBase package does this kind of mixing of base and grid
graphics; and also this behavior might be a side-effect of a more
serious bug.

Best regards,

The only device I've tried is quartz(), x11() crashed with rasterImage,
