..but Render to PNG (as opposed to preview) would be `openscad test.scad -o out.png --enable=manifold --enable=render-colors --render`

> @kintel I was confused about the `--preview` flag. Have now added the test, normal preview is fine, it's just the `--preview=throwntogether` that [looked funny](https://github.com/openscad/openscad/pull/5185/files#diff-7fd4542c55e81a1b2adb5fabc8c044af621b2ecfae91fd1584efe9b04a050cd8). The purpose of `--preview=throwntogether` is...

This is all fantastic stuff! I'm not even sure we need a separate experimental feature for it, as we can align this with the manifold feature itself. ..but let's focus...

Let me know if you think it's better to chase the stragglers in follow-up PRs; I can keep trying to break this for a while :)

PS! I'm working on some relatively light test framework refactor to make it clearer how CGAL vs. Manifold is being tested and which expectations differ. "light weight" as in no...

Let me fix a couple of stragglers first; shouldn't take more than a day or two. This is also solid enough that we can make this enabled under the Manifold...

@ochafik In case you have ideas how to address them: Issues I found related to manifold color support: #5216 #5217 #5218

@ochafik Manifold's hull should be improved now, so it's worth to take another shot at this.

@ochafik Is this ready to go? A bit swamped atm., but I can put it on my review list.
