/*
 * @name	GUIButton
 * @brief	- 	A button with a callback function which are called when running
 * 				the function GUI_CheckAllActiveButtonsForTouchEventAt() with
 * 				appropriate arguments.
 * 			- 	A button can have either one or two rows of text. No check is
 * 				done to make sure the text will fit inside the button so the
 * 				user has to make sure the button is big enough.
 * 			- 	The maximum length of the text is determined by the text
 * 				variable you send when calling the GUI_AddButton function. You
 * 				have to make sure you don't send any bigger text than this
 * 				using the GUI_SetButtonTextForRow function as that will
 * 				probably corrupt data! Think of it as static from when
 * 				compiling.
