input:  asset of a certain resolution (e.g. 200 x 200 pixels)

    case A:   5ft/ 50px grid cells
    case B:  10ft/ 50px grid cells
    case C:   5ft/100px grid cells
    case D:  10ft/100px grid cells

without any extra information:

    drop on A]  4 by 4 cells  (20 x 20 ft)
    drop on B]  4 by 4 cells  (40 x 40 ft)
    drop on C]  2 by 2 cells  (10 x 10 ft)
    drop on C]  2 by 2 cells  (20 x 20 ft)

    -> The image will just always take 200 by 200 pixels irregardless of grid settings and thus render different for every grid setting

with info that the image should represent 2 x 2 cells:

    drop on A]  2 by 2 cells  (10 x 10 ft)
    drop on B]  2 by 2 cells  (20 x 20 ft)
    drop on C]  2 by 2 cells  (10 x 10 ft)
    drop on C]  2 by 2 cells  (20 x 20 ft)

    -> The image will be resized, but to the wrong size if we differ from the default 1 cell = 5ft

with info that the image should represent 2 x 2 cells that are 5ft:

    drop on A]  2 by 2 cells  (10 x 10 ft)
    drop on B]  1 by 1 cells  (10 x 10 ft)
    drop on C]  2 by 2 cells  (10 x 10 ft)
    drop on C]  1 by 1 cells  (10 x 10 ft)

    -> Actually correct
