Title: parameters h_align and v_align

With this parameters, the user can choose the alignment of the crop.

I considered to use keywords, predefined values and 0 to 1 values, but, since css `background-position` already uses percentage, I guess it's better to keep this standard.

Thanks for the opportunity to help.
