[ODE] OPCODE vs. double

[Timothy J. Wood]

   I'm sort of worried since I've seen people on this list mentioned 
that D3D breaks their simulation (since it gets rid of the extra 
precision by default), but then OPCODE requires single precision.

   So, what's going to give?  Are we just supposed to abandon double 
support in ODE or should OPCODE be made to work with double for when 
you need precision more than space?  Can ODE be made to lose less 
precision in floats (seems unlikely)?  Other solutions?
