Missing spaces in LaTeX expressions when plotting using `latex2exp`

[colinbousige]

Hello,

See original post here where the author of latex2exp tracked the issue to arise from the httpgd plot renderer.

When plotting using httpgd and latex2exp, LaTeX expressions are missing spaces and are distorted. Doing the same plot in the normal R png renderer yields the expected result.

To reproduce in a vanilla R terminal:

library(httpgd)
library(latex2exp)
hgd()
plot(TeX(r'($\alpha$ and also $\beta$)'))

yields this:

instead of this :

library(latex2exp)
plot(TeX(r'($\alpha$ and also $\beta$)'))
