@Salkin975 I've opened the following branch for integration, and this PR to see that we keep this branch working and up-to-date with the main branch.:
https://github.com/maplibre/maplibre-gl-js/tree/mlt

I tried to copy over the code from your branch but I'm not sure this is the right approach to solve it.
Most of the code is duplicated between mlt and vector source when there's no real need to copy it.

I would recommend as an initial step to only try and make mlt work in maplibre without optimizing the buckets and other things.
Once we have it working with some basic tests for lines, fill, symbols etc, we can start implementing the optimizations that are needed.
What do you think?
