scaled-scene-buffer: restructure source files
Some checks failed
labwc.github.io / notify (push) Has been cancelled
Details

Browse source 
- Rename `scaled_scene_buffer` to `scaled_buffer`. This makes it clear
  that `scaled_{font,img,icon}_buffers` are implementations of it.
- Move the files from `src/common` to `src/scaled-buffer` as
  `scaled_icon_buffer` heavily depends on `server` and `view` etc.
