/*
 * @name	GUIButtonGridBox
 * @brief	-	A rectangular box with a title, close button, optional label
 * 				column and a grid of buttons.
 * 			-	When a button is pressed actionButtonPressed will be called
 * 				with the row and column for the pressed button as parameters.
 * 			-	The position and dimensions can be set using the object
 * 			-	There are various color choices for flexibility.
 * 			-	The buttons in the grid can have one row of text.
 * 			-	If a certain position in the grid should be empty, just don't
 * 				set that button's text to anything, or set it to 0.
 * 			-	The font is used for all elements of the button grid box.
 * 			-	titleHeight sets the height of the title bar and also the
 * 				height of the close button.
 * 			-	Dimensions for the button grid and optional label column are
 * 				calculated automatically according to the dimension of the box
 * 				and it's padding.
