Rebrand Bevy XPBD and Switch Solvers about bevy_xpbd HOT 2 OPEN

Is there any plan to use GPU for the physics engine? As I understand it, XPBD currently operates solely on the CPU, correct? Theoretically, this could significantly improve performance.

If so, at what stage of development is this? Looking at Bevy, they started using wgpu from the early stages of development. Would it be a good idea to take a similar step: a new solver (for example, TGS Soft) but focused on the GPU?

Bevy was built on wgpu from the very beginning, which meant most of the hard work of supporting WebGPU was already done

@unwx using the GPU is most likely not worth it; unless the shape of the problem is very regular, aka colliding a bunch of spheres or something, it'd be really hard to make the GPU happy about the branching for colliding all the different shapes. Apparently, PhysX does so anyways, but I feel like there wouldn't be much benefit in any case. A system for simulating particle effects on the GPU may be valuable though, but that's beyond the scope of this crate.
