Here's what I think is the offending PLIB code, at the top of
src/ssg/ssgOptimiser.cxx:
static float optimise_vtol [3] =
{
0.01f, /* DISTANCE_SLOP = One centimeter */
0.04f, /* COLOUR_SLOP = Four percent */
0.004f, /* TEXCOORD_SLOP = One texel on a 256 map */
} ;
Unfortunately, this array is not accessible from outside, so we cannot
simply modify it -- we'll have to patch. Try changing the first one
(DISTANCE_SLOP) to something like 0.001f and see if most of the
problems disappear. If so, then we can try to get the plib folks
either to change the default, or provide a way to modify this from
outside (say, through a function call).
All the best,
David
