v1.28.0

### Added
- **3D models are now a particle source.** Point Raster, Morph, Pegboard or Etch at a
  `.glb`/`.gltf` mesh or a `.ply`/`.splat` capture with the new **Model…** button, and it
  is re-made in that effect's medium — your own scan, as pegs or as scratched aluminium.
  Yaw, Pitch, Zoom and Ambient set how it is framed; meshes are shaded from their own
  surface normals, captures keep their captured colour. In Morph a model becomes a morph
  target you can blend to, via the new **Model** button in the target row. Models are
  saved and restored with presets, pose included.

### Fixed
- Swapping to a particle source that samples fewer points left the previous source's
  particles stranded on screen — pegs from an old model pose kept standing after a
  re-sample. The tail of the source buffer is now cleared, so they die as intended.
