Closed doors in minimap

[tiger_eye]

I think it would be a great help if closed doors were distinguishable from walls in the minimap. (Oddly enough, on some levels, open doors are distinguishable, but closed doors still are not).

I also sometimes have a difficult time seeing the "blue" dot for items in the minimap. I don't have time right now to make a suggestion, ' else I would.

While we are at it it would also be great if explored space would be painted by other color.

One problem with the blue squares is that the little map image doesn't stretch right to the edge of the black box, and the blue squares are hard to distinguish against a black background. If the map image were stretched to always fill the space then it might make things a little better.
