I noted that. I think it should be affected only by \mathdir changes,
when \mathdir is TLT, I think the user expects math to be done the way
TeX usually does it. I checked FarsiTeX[1] and RyDArab[2] typeset
samples, and both put the equation in the middle of the page (in 
FarsiTeX math is always LTR, while RyDArab can typeset RTL math as
well). I thought that equation number position should be swapped, but
FarsiTeX don't swap it, so I think it'd be better controlled at macro

I think the current behaviour of TRT math is OK.
