Message

UNIT_CELL_SIZE is a control that represents the size of a cell (pixel).
We required a bit of boilerplate to add this control :)
- New way to init compount controls
- New control type

Thanks to Hans, Jacopo and Philipp for your help.

You might want to see the series at my github repository if needed.
