There is a bug when you want to put the image to the standard proportions:
Ax = 0
Ay = 0
Bx = 1
By = 0
Cx = 1
Cy = 1
Dx = 0 <--- bug
Dy = 1
If I set Dx to 0 the image disappears.
I have to put 0.0001 for it to work.
If I deselect the image then I reselect it and there Dx is at 0!
Would it be possible to fix this bug?
Thank you again and nice job!
