Repel option for `type_text()`?

(Aside: it would be cool if we could support some kind of repel / spread functionality in type_text().)

For inspiration, I recently came across this nice example using the textplot() function from the wordcloud package. The core functionality looks pretty straightforward, though we would obviously need to credit and/or check licensing restrictions.

library(wordcloud)
#> Loading required package: RColorBrewer

mtcars2 = transform(mtcars, make = row.names(mtcars))

with(mtcars2, textplot(wt, mpg, words = make))

# bump axes limits to catch edge labels
with(mtcars2, textplot(wt, mpg, words = make,
                       xlim = range(wt)*c(0.96, 1.04),
                       ylim = range(mpg)*c(0.96, 1.04)))

Nice example. Given that the code is nicely encapsulated in wordlayout() but depends on C++ code for checking the overlap (plus: LGPL-licensed), I think I would just make wordcloud a Suggests dependency for this option.
