Detailed Description

BoxTriColStruct Scratchpad variables for the OBBox-Triangle collision detection functions. One instance of this structure will be used for all of the local variables and its pointer will be handed of to various inline functions for the axis tests. Note that much of the code needs the un-normalized triangle normal. For this reason, I have to compute N rather than copying it from the triangle. (commenting this to avoid re-generating a difficult to find bug that I had)

Note that the MaxFrac variable starts negative so that we can accept slightly negative fractions (interpenetrations). But we clamp the returned result to 0.0 so that we never allow an object to get more embedded, just to possibly break itself free if it is within the epsilon. This is important because sometimes objects seem to intersect simply due to floating point roundoff error...
