Rotation and translation can be represented as simple 3x3 matrix, with every coordinate being run through the single transform. Pre-creating matrixes that combine transforms makes it easier to place rotations...

I've added a super-simplified (but slow and error-introducing) implementation to get the basic pieces into place, where the coordinates are immediately rotated and applied to both `current_position` and `destination`. The...

Let's revisit this after completion of the Fan Class refactor in #24092 – which should be in more complete shape pretty soon.

It would be cool to have a CI test for this and the Simulator, but it needs to download and build SDL2 as part of the test. I've Googled around...

This is still interesting, though it might be more suitable as an addition to the MarlinSimUI project. I went ahead and rebased it in case anyone still wants to experiment...
