Diagonal Mirror Questions

One way to tackle a problem like diagonal mirroring is to figure out what you want to do on some small samples. If you don't know how to specify something in English and get the right result you won't be able to do it in Java.

As an example here is a 2-d array of numbers (3 rows and 3 columns)

1	2	3
4	5	6
7	8	9

After diagonal mirroring (around a mirror from x=0,y=height-1 and
x=width-1 and y=0)

1	2	3
4	5	2
7	4	1

Another example is a 2-d array of numbers (4 rows and 4 columns)

1	2	3	4
5	6	7	8
9	10	11	12
13	14	15	16

after diagonal mirroring we have

1	2	3	4
5	6	7	3
9	10	6	2
13	9	5	1
