Gabriele, you remind of myself. You have been through a life grinder and 
somehow survived. We must learn from our life and all become much 
stronger in ourselves. Don't apologized for being you.

I believed that this rotation or skew (I think you think the same) is 
the painting layer of background-image. This is the same painting layer 
as CSS gradients. Apart from my previous list message [1] where I 
mentioned about blur happening to background-image, I also believe that 
this painting layer is the layer where masking (positive or negative) 
can be done. Could we possibly use background-origin as a way to rotate, 
skew or mask and leave background-image for blur and other affects? This 
would allow two operations to happen.

Example: A blurring of background-image with masking on background-origin.
