See Matt Keeter's propero challenge for details.
The prospero example converts propero.vm into a WGSL shader and then evaluate distance values in the XY plane using shaders/sample_plane.wgsl.
Workgroups size is set 16x16 and is not optimized yet.
To run this example, use the following command.
cargo run --example prospero --releaseHere a few sample timings for the few machines I could test it on.
