a storage for a a tiled area
An array of tiles width * height is maintained here. The tiles can be filled using scaning functions which take basic primitives as input. Later on the covered tiles can be extracted as a list of rectangles which cover the same area but with less rectangles in general.

fill tiles covering the rect given
The rect formed by x,y,w,h, is divided over the tiles, filling the the part of the tiles that are covered by the rectangle.
| x | x of rectangle |
| y | y of rectangle |
| w | width of rectangle |
| h | height of rectangle |
| expand | if true keep existing filled tiles, else clear all. |

generate from files tiles a list of semi optimal covering rectangles
The tiles are iterated in horizontal rows, combining filed tiles found in the rows when at same height and connecting with the previous tile. The found rect is then combined a rectangle already found in a previous row.
