stencil support for the pixel editor

[skjoldbroder]

Hi,

I've got another little suggestion for the pixel editor: stencil support. This is the ability to isolate 1 (or more) colours as a mask within which to paint. A use case for this could be: First I draw a logo silhouette in white on a black background - once that reads nicely the way I want it, I pick white as my stencil colour and I can paint in all of the shading, without worrying about changing the silhouette.
One I'm done with shading, I would then disable the stencil again, so I can tackle antialiasing on the border edges.

it could also work reversely, where you "write protect" colors so they cannot be painted over (in my example above, I would then write protect everything except white).. this might be simpler to implement in the TIC80 UI, but I will leave this up to you. Thank you for the great fantasy console :)

all the best
