#1047 Advice on how to place tiles more beautifully

[x0r]

I saw that the program places tiles simply and not nicely.

Size of the wall 2100mm
Tile size 500x200mm
The algorithm to improve it is as follows:

1. It is necessary to calculate how many whole tiles fit in one row.
   2100//500=4 tiles
2. Remove one tile.
   4-1=3 tiles
3. Place the rest of the whole tiles in the middle.
   I mean 3 tiles.
4. Place the cut tiles on the left and right.

This will make the tiles look nicer on the walls.
People will be able to calculate the required number of tiles.
