* To test this we need to test all combinations of these parameters
* with drawImage.
* If we have a source rectangle with vertices, sA, sB, sC, sD
* there are 4 combinations : sA+sD, sD+sA, sB+sC, sC+sB.
* Similarly for the destination with vertices, dA, dB, dC, dD
* there are 4 combinations : dA+dD, dD+dA, dB+dC, dC+dB.
* Thus we need 16 calls to test all combinations.
* Note that we set the source area coordinates (x and y -20->80)
* to be beyond the image size (50x50) so clipping is always needed.
