When you insert a sprite into the OT at a certain priority, that sprite
is joined to the HEAD of the linked list that makes up the OT. Therefore
what gets drawn first is what is at the start of the list.
If you want it the other way around, then insert your rects backwards.
If you can't do this, then insert the 'nearer' rects at lower priorities,
and the 'further' rects at higher priorities. There's a related post
from me somewhere which explains priorities in some detail.

Cheers,
