here it can be seen visualized
the correct transformation of the drawing was achieved by using the method of 3 homing points and use that to calculate two triangles. (problem is that it tranforms 99% of the points correctly but 1% them come out as nonsense, you can see it by several lines just shooting to a corner randomly in the correct drawing)

so i want to use the matrix transformation which does all points correctly, and is faster too, but there is this strange position offset
