This is a replacement for #1376. The original thinking was that we will promote the non-float attributes to float which was a complex and poor performance solution. The better solution is to change the shader to take non-float attributes. Fortunately, this shader processing is already happening for WebGPU on the JS side. @Popov72 factored out the shader processor on the JS side for WebGPU to also work with Babylon Native, which also includes code that aligns the buffers to 4-byte boundaries. This native PR ties everything together and removes all the promote to float logic we had earlier to try to handle non-float attributes.
This change includes updating Babylon.js to 7.7.2. Using an older version will result in a
console.errorif non-normalized, non-float vertex buffers are used.
