We often introduce bugs when the layout of pages was unintentionally changed (MAGNOLIA-5029 -> MAGNOLIA-5132) or the dialogs were broken due to changes in javascript (MAGNOLIA-4829 -> MAGNOLIA-4895). We should avoid this by comparing sample screenshot with current ones. This will also automate page rendering/layout QA.

• If the layout will be changed intentionally (and this should be not so often), new samples will be uploaded.
• To avoid fail due to changes in colors the screenshots will be compared as black&white images.
• We should be able to set threshold (% of wrong pixels) which will be acceptable to avoid problems with minor changes in layout.
