Summary

• Adds srcNumSplats and dstNumSplats uniforms to processing shaders
• Automatically skips padding pixels in the shader wrapper (texture may be larger than actual splat count)

Details

GSplatProcessor now automatically discards padding pixels before calling the user's process() function. This matches the behavior of rendering shaders and removes the burden from users to handle texture padding manually.

The following uniforms are now available in processing shaders:

• srcNumSplats - Number of splats in source resource
• dstNumSplats - Number of splats in destination resource

These complement the existing splatTextureSize and dstTextureSize uniforms.
