export opt_tm_markers()

Required to have examples passing!

Commenting out for now the only remaining one that doesn't work.

data("NLD_prov")
NLD_prov$x = seq(10, by = 5, length.out = 12)

tm_shape(NLD_prov) + 
	tm_symbols(size = "x", size.scale = tm_scale_continuous(values.scale = 4)) +
	tm_text(text = "x")

All other examples (except dontrun work currently!)

#860 is fixed: is this still needed?

Yes, I reverted unnecessary changes, but you can squash merge this (or commit the remaining changes to master yourself) to avoid ugly history. https://github.com/r-tmap/tmap/pull/859/files

• export opt_tm_markers + remove unneeded line
