Draws a colored rectangle.
Draws a rectangle. If [code]filled[/code] is [code]true[/code], the rectangle will be filled with the [code]color[/code] specified. If [code]filled[/code] is [code]false[/code], the rectangle will be drawn as a stroke with the [code]color[/code] and [code]width[/code] specified. If [code]antialiased[/code] is [code]true[/code], the lines will be antialiased.
[b]Note:[/b] [code]width[/code] and [code]antialiased[/code] are only effective if [code]filled[/code] is [code]false[/code].
