There are three options for drawing a Rectangle: OUTLINE, FILL and ROUND.
The default option is OUTLINE with Square corners. Once you select FILL, all subsequent Rectangles will be drawn filled with color until you select OUTLINE.
ROUND draws a rectangle with Rounded corners that can be in either Outline or Fill. You must select ROUND each time you want to draw a rounded cornered rectangle.
Rectangles can be animated to fill with color, change color, change size, move and display frames.
