usepoly default breaks 3D plotting in CairoMakie

we have the usepoly kwarg which switches plotting to the workaround for the CairoMakie mesh bug. At the moment, it is enabled automatically for all CairoMakie particle plots by default, including 3D ones. Since the workaround only works for 2D, users need to be aware of the problem and manually specify usepoly = false for 3D plotting.
