Write a program to draw the interface of the Game of Tetris, as shown in Fig. $1\mathrm{.}15.$ The game involves playing with different shapes, each composed of four squares. The main area $($large rectangle$)$ should be sized as $1020$ squares $($i$.$e$.10$ squares wide and $20$ squares high$).$ The small rectangle on the right shows the $$next shape$$ that will soon appear in the main area $($a red $$L$$ shape in the example$).$

Complete only the following tasks for this homework: $$ Draw everything shown in this figure $($the position of each component, e$.$g$.$ rectangle, does not have to be exactly the same as in the figure$).$ If the mouse cursor moves inside the main area, $$PAUSE$($in a large font$)$ will be displayed; and if the cursor moves out of the area, $$PAUSE$$ will disappear. $1\mathrm{.}15$ The Tetris interface
