Comment (by daltonrooney):

 Thanks so much to Victor, this feature is something I've really been
 looking for in WordPress. I did find a small bug and hopefully a
 satisfactory solution. The cropped and non-cropped images are both created
 with the same dimensions, so if the cropped image already exists and you
 try to specify the non-cropped image instead, the cropped image is still
 returned. My solution is to calculate the final dimensions of the image
 earlier on.

 Just before this:

 {{{

 $cropped_img_path = $no_ext_path.'-'.$width.'x'.$height.$extension;

 }}}

 Add this:

 {{{

 /* Calculate the eventual height and width for accurate file name */

 if ( $crop == false ) {
    $proportional_size = wp_constrain_dimensions( $image_src[1],
 $image_src[2], $width, $height );
    $width = $proportional_size[0];
    $height = $proportional_size[1];
 }

 $cropped_img_path = $no_ext_path.'-'.$width.'x'.$height.$extension;

 }}}
