Dot:
Notes: If you adjust the size you will have to adjust the position to suit.
Example:
DrawPoint(CenterX-10,CenterY-10, 10, 10, Green);
The size is now 10 so i -10 off the XY position to suit.
//DrawPoint(XPosition,YPosition,Width,Height,Color);

Cross Crosshair:
Notes: XPosStart YPosStart starts the line and then XPosFinish YPosFinish is where the line will be drawn too.

Now that we have the main ones you can start merging them and making your own ones.
You have all the functions so ill just give your a picture and the drawing code.
