Ok, everything before the first number is ignored!

The idea here is simple - every nonnegative number
corresponds to a gridspot.

Any character after the number gives the orientation.

Now more detailed:

The first two numbers in the file are the gridspots of the
player and the rock, respectively.

Next come the charts. Each one is given by two numbers
representing height and width followed by a table of
positions (oriented gridspots). Positions which are
adjacent in the input will be patched together.

After the first empty chart come the colors. Colors are
set by specifying an inclusive range of gridspots to be
colored, along with a number specifying which color the
range should be colored.

(To reduce brain breakage from the sample atlas, try
switching the six-f to a six and the nine to
a nine-b.)
