Missing: Set coordinates for cropping

[creativecat]

Currently, when cropping a image, you always start at 0|0. Would be great if you could add the additional option to crop a different area. Something like:

public function resize(
    $max_width,
    $max_height,
    $method="fit",
    $cropAreaLeftRight="c",
    $cropAreaBottomTop="c",
    $jpgQuality=75,
    $dst_x=0,
    $dst_y=0
) {

You could also check if is_numeric($cropAreaLeftRight) and is_numeric($cropAreaBottomTop) and when they are both numeric use those values for positioning the cropping area.

Feel free to implement the change and make a pull request.
