Retroday outline

Summary

SUMMARY: Interface "add transparency to retrodays"

Purpose of change

retrodays tileset is my favourite but, all the tiles have a black background thus rendering all objects like a black square with the object drawn on that.
the problem is, when you have and object on top of a larger one, like a lighter on a table,
the lighter gfx and its black square background, prevent you to see the table underneath.
it make it look like the table is missing a whole chunk. to the point that if there is few objects (3 or 4) on the table you cannot distinguish there's a table at all.

so i removed the black squares, and left instead a black outline around the contours of the objects.
other tilesets have transparency, so i made it for retrodays too.

Describe the solution

i removed black squares around tiles, and left a black outline instead.

Testing

i have been playing with that for quite some time.

Additional context

in general look for objects on top of bigger objects, like the tables and sofas:
