Bug with wgsl on some filters (v8)

filters/filters/pixelate/src/pixelate.wgsl

Lines 16 to 30 in a287d90

	@group(0) @binding(1) var uSampler: texture_2d<f32>;
	@group(1) @binding(0) var<uniform> pixelateUniforms : PixelateUniforms;
	@fragment
	fn mainFragment(
	@location(0) uv: vec2<f32>,
	@builtin(position) position: vec4<f32>
	) -> @location(0) vec4<f32> {
	let pixelSize: vec2<f32> = pixelateUniforms.uSize;
	let coord: vec2<f32> = mapCoord(uv);
	var pixCoord: vec2<f32> = pixelate(coord, pixelSize);
	pixCoord = unmapCoord(pixCoord);
	return textureSample(uSampler, uSampler, pixCoord);

textureSample wants a texture_2d, sampler and vec2

This is wrong on a lot of filters, and this is the fix:

 @group(0) @binding(1) var uTexture: texture_2d<f32>; 
@group(0) @binding(2) var uSampler: sampler;
 @group(1) @binding(0) var<uniform> pixelateUniforms : PixelateUniforms; 
  
 @fragment 
 fn mainFragment( 
   @location(0) uv: vec2<f32>, 
   @builtin(position) position: vec4<f32> 
 ) -> @location(0) vec4<f32> { 
  let pixelSize: vec2<f32> = pixelateUniforms.uSize;
  let coord: vec2<f32> = mapCoord(uv);

  var pixCoord: vec2<f32> = pixelate(coord, pixelSize);
  pixCoord = unmapCoord(pixCoord);

  return textureSample(uTexture, uSampler, pixCoord);

Thanks @pagoru ! I have updated on all filters accordingly 🙏
