Adds growing and shrinking digits animation to Smart Countdown 2.0 module. Growing: Current digit image grows in size and at the same time changes opacity from 1 to 0 becoming invisible at the end of transition. The new digit grows from 0 in the center of digit frame to full size. Shrinking: Current digit image shrinks to 0 size in the center of digit frame. The new digit starts double-size of the frame and shrinks to normal size and at the same time changes opacity from 0 to 1 (fade-in) becoming completely visible at the end of transition.
