Isn't this better suited as separate mod?
(I think I've seen it implemented already, btw. (And I've attempted it myself (but wasn't satisfied because of the limit on texture name size IIRC).))

Also, if this is added, it probably would make more sense as separate node.
And nowadays, one can use [png for cheaper texture generation and shorter texture names.

Isn't this better suited as separate mod?

It's a very small addition that I thought it would be OK for displaying things very quickly.

I think I've seen it implemented already, btw.

Digiscreens already exists, but it has a lower resolution (16x16 vs 56x48) and it is intended to be used with more screens to make a bigger one, while this implementation is intended for one single screen and quicker usage.

Also, if this is added, it probably would make more sense as separate node.

I also thought initially that making a new node made more sense, but then I wanted to try on giving more functionalities to the same screen and see how it would be. I personally think that it is not bad.

I'll take a look, thanks.
