WIP : Attempt to change zoom level of the minimap

[vadim-soude]

I want to change the zoom level of the minimap (like the vanilla way) meaning each pixel don't represent one block but, for example, four.

For now, I changed the way the flat render work, the minimap is scaled down the way I want, but I have an issue with player movement.
The minimap scrolling still goes at the same speed as the player, when it's a 1:1 ratio it's not an issue, but now it's a 1:2 ratio and it glitches out. When I go to the end of a 1:1 classic section of the world (a 128x128 zone) the visual snap to the beginning of the section and everything end-up is misaligned.

I hope someone can figure out how to fix the move part, I tried a lot of things, but everything broke 😞

Known issue : Since we are pulling blocks from a 256 by 256 zone (16*16 chunks) instead of 128 by 128 zone (8 by 8 chunks) everything is slower and the performances are way worst but it "normal"

And technically I cheated a little, I just took the first block of the four for each pixel instead of the most frequent, but I think it's better for performances.
