Allow scaling display panel icon map view, so we can use them as pixels

[warbaque]

TL;DR

Enable using display panels as pixels in map view.

What?

Currently display panels can be used to draw icons on map view.
I propose that we could scaling that icon size from 1 tile to current 15x15 tiles which would allow for more flexibility when drawing on map and enables rudimentary dot-matrix displays.

It would also be nice if we could could use single colors instead of icons.

Why?

Dashboards are cool!

Display panels are currently ok for drawing icons including letters and digits on map, but I would prefer if we could scale them down, so we could also use icons as individual pixels for more freeform displays.

2.0 rails broke my map viewable dashboard displays.
Nuclear dashboard example:


Old rails allowed placing signals with 1 tile spacing which worked really well for map view displays

With new diagonal rails this is not possible any more

This was always a bit janky, but it was great for drawing red/green pixels on map. Now that we have display panels, I think that they would be great for this.

Alternatively we could add option to lamps to render their color on map.
