Change 'width' from
        If both the width and heigth is set and one of the numbers has an "m" after it,
        the proportions will be preserved and thus width/height will work as max-dimensions

Change 'width' to
        If both the width and heigth is set and one of the numbers has an "m" after it,
        the proportions will be preserved and thus width/height will work as max-dimensions
        for the image - image will be scaled to fit into width/height rectangle.

        If both the width and heigth is set and at least one of the numbers has a "c" after it,
        cropscaling will be enabled; that means the proportions will be preserved and the      
        image will be scaled to fit around a rectangle with width/height dimensions.     
        Then, a centered portion of the image (size defined by width/height) will be cut out.
        The "c" can have a percentage (-100 ... 100) after it, which defines how much the cropping
        will be moved off the center to the border.
        Example
        This crops 120x80px from the center of the scaled image:
        .width = 120c
        .height = 80c
        This crops 100x100px; from landscape-images  at the left and portrait-images centered:
        .width = 100c-100
        .height = 100c
        This crops 100x100px; from landscape-images at the left and portrait-images at the top:
        .width = 100c-100
        .height = 100c-100
        This crops 100x100px; from landscape-images a bit right of the center and portrait-images a bit upper than centered:
        .width = 100c+30
        .height = 100c-25

Change 'height' to
        See width

 I would like to add a little diagram that says more than thousand words
 if that's possible (will have to prepare that first though)?
