navigation in lattice plot

[cbarbu]

Problem as the drawGrob function is not accessible:
Error in do.call(fn, alst) : could not find function "drawGrob"

Additionally the resetting of xlim/ylim are likely messed up.

We would want the basic example to work:

require(stats)
Depth <- equal.count(quakes$depth, number=8, overlap=.1)
xyplot(lat ~ long | Depth, data = quakes)
update(trellis.last.object(),
strip = strip.custom(strip.names = TRUE, strip.levels = TRUE),
par.strip.text = list(cex = 0.75),
aspect = "iso")
zm()

I'm not going to do that any time soon but if you are interested please do and then make a pull request!
