    Description

      Prevent flooding the system with multiple calls to .imaging:

      /magnolia/.imaging/focalpoint/999x999/dam/jcr:c322407c-02b7-4fbb-ab8f-8a61dbc349a2/Carrousel.jpg
      

      A hacker would call this url incrementing "999x999" from 1 to infinite.

      So that the imaging workspace would overflow or would request a high CPU usage from cropping the images.

      Notes:
      We should configure different breakpoints (bp) and the imaging/focal point module should return the resources that equals is is just above this bp.

      For example, we could configure:

      <=400 returns 400px
      <=800 returns 800px
      <=1024 returns 1024px
      <=1200 returns 1200px
      <=1600 returns 1600px (this is the last the the greatest)
