Investigate object on-top or wall layer

[xopr]

Find a way to draw object on top of the walls (currently part of overlay); either:

• always ontop objects
• intermediate layer (walls): wall item draw over character/object if player position is on wall rect

[xopr]

I had a stab at this and came to the conclusion that splitting the top in 2 is not straightforward:

• player is roughly 2 blocks high
• player moves in blocks of 1
• when in front of a wall, player should be rendered fully (2 blocks)
• when behind the wall, overlay should be rendered on top

Since there is a difference it needs either to detect whether player is on a transparent pixel/block, or it needs to detect the blocking tile attribute to determine its logic
