Description
Currently the implementation only supports textures that are:
- 2d
- have a format that can be sampled as
floatorunfilterable-float
Since those are some pretty heavy restrictions we should expand it by:
- allowing for any texture dimension
- creating a compute pipeline downsampling implementation for textures that cannot be sampled
As a part of this task I would also measure the performance of downsampling using a sampler inside a fragment shader vs a compute shader implementation.

Research direction
Start by locating the existing generateMipmaps() implementation and the TgpuTextures handling for texture dimensions and sampleable formats. Compare the current fragment-shader approach with a compute-shader downsampling approach, then measure both. Done means mipmap generation supports every texture dimension and formats that cannot be sampled, with performance results recorded.
