            Minimum Size of the Component.
            Some Layouts will automatically
            resize Components; this prevents
            the Size from going below a
            certain value.

            Maximum Size of the Component.
            -setPreferredSize(Vec2f): Determine
            the Preferred Size of the Component.
            This is what the Component will
            be displayed at unless changed by
            another Component (such as a 
            Layout).

            The word Text will be displayed
            in this case.

            Functions specfic to Button:
            -setText("DesiredText"): Determine 
            the Button's text.  It will read
            DesiredText in this case.
            -setFont(FontName): Determine the 
            Font to be used on the Button.
            -setTextColor(Color4f): Determine the
            Color for the text.
            -setRolloverTextColor(Color4f): Determine
            what the text Color will be when
            the Mouse Cursor is above the 
            Button.
            -setActiveTextColor(Color4f): Determine
            what the text Color will be when
            the Button is pressed (denoted by
            Active).
            -setAlignment(Vec2f):
            Determine the Vertical Alignment
            of the text.  The value is 
            in [0.0, 1.0].
