Reverse trackers middleware

[julik]

've been wondering if you can implement a feature that can reverse the trackers.
For example....

Tracker 1
1f 10 x 10 y
2f 9 x 9 y 
3f 8 x 8 y
4f 7 x 7 y
5f 6 x 6 y

to....

Tracker 1
1f 6 x 6 y
2f 7 x 7 y 
3f 8 x 8 y
4f 9 x 9 y
5f 10 x 10 y

something like this~

programs like boujou(4) cannot solve backwards... it only builds the initial solve from frame 1 !! only =(
so to solve from the back, we reverse the plates and we need the trackers to be reversed as well!
