Is there a way to change the thickness of the line-type markers (e.g. `:xcross` and `:cross`) in Plots.jl? I’m using the GR backend, if it matters.

I’d expect the following to give a marker with pretty thick lines, but neither the `markerstrokewidth` or `linewidth` attributes seem to affect the marker. `markerstrokewidth` does seem to affect the stroke of some other marker shapes like `:diamond`.

```julia
scatter([5], [5], xlims=(0,10), ylims=(0,10),
        markershape=:xcross,
        color=:black,
        markerstrokewidth=5,
        linewidth=5,
        markersize=20)

```

Gives:

Does it affect all unfilled markers?
