/** This program draws scaled targets for the biathlon so you can see how tiny
they actually are. It allows you to make targets that will fit inside your
room.
"The target range shooting distance is 50 metres (160 ft). There are five
circular targets to be hit in each shooting round. When shooting in the prone
position the target diameter is 45 millimetres (1.8 in), when shooting in the
standing position the target diameter is 115 millimetres (4.5 in)."
The size of the target probably won't be accurate on screen, as almost no
operating system reports screen resolution accurately. You should print the
target for accurate results. */
