    8889'''Caching ImmImages multiplied by recently used colours''' will make drawing of images above other elements (including background) faster 
    8990 * A new private field will be added in ImmImage to store the image multiplied by recently used colours - HashMap<ImmColor, ImmImage> colorImgCache. 
    90  * A new method for multiplying the image by given color will be added in ImmImage. It will check if the image multiplied by the given color is already cached. If it is it will return the cached value. If not - it will compute it and put it in the cache.  
    91 There is a method that multiplies the image pixels by a color in ElementHelper, it will be copied here and removed from ElementHelper. 
     91 * The method transformColors(ImmColor) will check if the image multiplied by the given color is already cached. If it is it will return the cached value. If not - it will compute it and put it in the cache.
