[R] lattice/postscript/pdf: size of striptext and xlab and other strings

[Wolfram Fischer]

____PROBLEM_________________

When comparing the output from:
	data(barley); dotplot(variety ~ yield | year * site, data = barley)

run with R 1.8.1 and with R 1.9.0, one gets different
sizes of striptexts and xlabs.

____OBSERVATIONS____________

- The result is the same when the output is redirected
  by postscript() or by pdf().

- trellis.par.get() shows the same cex-values in both R versions.

____QUESTION________________

How can I get the same text sizes as in R 1.8.1 for lattice output
using R 1.9.0? (And hopefully reuse older scripts without changing
their code?)

Thanks Wolfram
