Jeroen Bakker 2e19649bb9 Sequencer: Performance image crop transform.
During transforming an image, a matrix multiplication per pixel was done.
The matrix in itself is always linear so it could be replaced by two additions.

During testing in debug builds playing back a movie went from 20fps to
300 fps.
