/**
 * Draw a template for an effect with a cone area. Make the template show the squares that are effected, not just draw a
 * circle. Let the player choose the vertex with the mouse and use the wheel to set the radius. Use control and mouse
 * position to direct the cone. This allows the user to move the entire template where it is to be used before placing
 * it which is very important when casting a spell.
