I am plotting a cylinder in makie like so:

```julia
julia> cyl = GeometryBasics.Cylinder(GeometryBasics.Point(0.0,0.0,0.0),GeometryBasics.Point(0.0,1.0,0.0),.5)
Cylinder3{Float64}([0.0, 0.0, 0.0], [0.0, 1.0, 0.0], 0.5)

julia> mesh(cyl,transparency = false, overdraw = false, color = :cyan) 

```

This is coarsely faceted. How can I increase the number of facets that Makie plots? This is not an intrinsic property of the `GeometryBasics.cylinder` object. It is computed on the fly by the `faces` function, which I’m guessing Makie calls to get the mesh faces for the object.

But the `Makie.mesh` function doesn’t seem to have a keyword argument to control the number of faces to use when triangulating the cylinder.

I looked at the `GeometryBasics.mesh` function, thinking I could create a polygon mesh myself with a large number of faces. But this function doesn’t seem to have a keyword argument for controlling the number of faces either.

How can the number of faces used to plot these geometric primitives be increased?

Thanks to @sdanisch, I learned this trick to accomplish this the other day

```julia
Makie.normal_mesh(Makie.Tesselation(Makie.GeometryBasics.Cylinder(p1, p2, radius), num_facets))

```
