Update README.md to fix installation error
Added a note about needing to install libgles-dev package if you get an error during install.
thanks. (it's probably missing a few other Gio dependencies, though)
perhaps we should "guard" vg/vggio behind a // +build vggio build tag, so go get gonum.org/v1/plot/... is kept "pure-Go" ?
@kortschak
Yeah, I'm not sure. That places an obstacle to use of the package that causes its own problems.
We should also decide whether we want to test on travis, since we have minutes back. I'd prefer not to since we're half way through what we have and they are more valuable for testing gonum/gonum on arm64.
Thanks all. Just for reference, I experienced this on Pop!_OS 20.10; and it was the only error I experienced during install.
