Function g3_DrawBox

renderer/HardwareDraw.cpp:416–431

Draw a wireframe box aligned with the screen. Used for the editor. Parameters: color - the color to draw the lines pnt - the center point rad - specifies the width/2 & height/2 of the box

//					pnt - the center point
//					rad - specifies the width/2 & height/2 of the box
