I expect to see Fira Code’s ligatures, but all text is separate

For the same reasons as in #23 this is not supported by cairographics. See #23 for a new branch that supports complex font shaping via Harfbuzz which also includes ligatures. I'll close this and track the rest in #23.

library(Cairo)
CairoFonts(bold = 'Fira Code:style=Regular')
Cairo(dpi=100)
plot(sqrt, main = 'foo <- bar != baz')
dev.off()
