If this makes sense, I'll go ahead and add tests etc. |

Some tests would be nice.
What about the PT[outer;]?
There was a problem hiding this comment.
That is fine, since points_flat contains the original points.
Will add some tests!

Description
Fixes MakieOrg/GeoMakie.jl#282
Previously, if you had 2D polygon and a 2D -> 3D transform func, the points would be transformed, and the resulting Point3 would be coerced back down to Point2. This is likely also why a lot of the triangulation was wrong.
This PR removes the element type constraint on the array returned from
apply_transform, thus allowing 3D points to stay 3D.I have a suspicion that if we merge this, it will break plotting polygons in 3d. It might need a very basic generic overload of
GeometryBasics.earcut_triangulatefor arbitrary dimensions, to restrict to 2D - at least for now.Type of change
