Dug a tunnel into the side of the mountain...
The engine now supports brushes for adding, removing, and painting multiple voxels at once.
Also added a micro heads up display at the bottom so toggling between voxel types and brushes is not fully an exercise in memorization.
There are still a few bugs and, now with larger persisted worlds, the frames-per-second (fps) is quickly dropping out of the ~60 range. Nonetheless, the engine is feeling more capable.
Working a bit on terrain generation. Turns out it can be a lot more fun working on this in native desktop with Rust rather than WebGL given the runtime limitations of the latter.
Added the ability to write Rust "scripts" (basically crates that the engine will run to get model output from) and added a voxel terrain with some basic procedural noise. I think of it as a "script" since it uses a blanket important use scriptlib::*; which brings in a lot of utilities to keep the code itself concise.
Also switched the WGPU to prefer linear RGB color until I progress a bit further and want to handle sRGB correctly.
