As there are pipeline to resize images, to force images in a given square, it would be nice to have pipeline to crop images.
example :

• _resources-images/*_max*x.* force the image to enter in the given square (keeping ratio)
• resources-images/**x.* resize the image (whatever the ratio)
• _resources-images/*. keep the original image
• NEW _resources-images/*_crop*x.* act as a min size for width and height, but then crop it to the given square. The crop should be centered
