* basic working wgpu @ webgl on websys * fix glow compile error * introduced WebPainter trait, provide wgpu renderstate * WebPainterWgpu destroy implemented * make custom3d demo work on wgpu backend * changelog entry for wgpu support eframe wasm * remove temporary logging hack * stop using pollster for web we're actually not allowed to block - this only worked because wgpu on webgl doesn't actually cause anything blocking. However, when trying webgpu this became an issue * revert cargo update * compile error if neither glow nor wgpu features are enabled * code cleanup * Error handling * Update changelog with link * Make sure --all-features work * Select best framebuffer format from the available ones * update to wasm-bindgen 0.2.83 * Fix typo * Clean up Cargo.toml * Log about using the wgpu painter * fixup wgpu labels * fix custom3d_wgpu_shader ub padding * remove duplicated uniforms struct in wgsl shader for custom3d * Update docs: add async/await to the web 'start' function Co-authored-by: Emil Ernerfeldt <emil.ernerfeldt@gmail.com>
