Description

Ultibo Console Interface unit

Note:

Console coordinates X,Y are based on either pixels or characters depending on the console mode (Pixel or Character)

Console coordinates begin at 0,0 and extend to Width - 1, Height - 1

Console Window coordinates X,Y are always based on characters, beginning at 1,1 and extending to Cols,Rows
