<h2>Description:</h2>
This class represents a display card in ClanLib. It is mainly used to set the videomode, flip the display and do simple graphics operations such as filled rectangles or drawing lines.<br><br> If you're always only using one display card at the time, you may want to consider using the static functions in <a href="CL_Display.html">CL_Display</a> instead. They do exactly the same, but operates on a selected display card instead (default the primary card). This saves you from passing around a pointer to the displaycard.<br><p>
