This task has been done and is pushed to the main repo. The various warpings are now options and users can specify their value and call them any number of times. The final warping matrix will be calculated internally.

Two options (`--rotate' and `--scale') have been added to ImageWarp so the user doesn't have to manually type the matrix each time they want to do simple operations like this.

This does not complete this task, because for now, they are mutually exclusive: only one can be run with each call to ImageWarp. But the infra-structure has been improved so implementing the final stages of this task is not too difficult, see the commit message for more.

Add options to read all the warp parameters separately (for example translate by X, then rotate by θ and scale by 4 times) and build matrices and multiply them internally.

In this manner, the user doesn’t have to calculate the final matrix prior to running the program. Currently ImageWarp can only accept the final matrix. This can be useful in scripts.
