Summary0004880: Bad normals produced by .ASE exporter
DescriptionDarkRadiant ASE exporter writes some bad values for normals (-1.#IND, -nan(ind), nan). Not sure how the engine handles NaNs, but among already existing TDM+FMs models, every fourth DR-exported .ase is affected.
Steps To ReproduceI could reproduce it by just making a cylinder out of a 1x1x1 brush.
Additional InformationThese were produced with exporter v0.9 (latest at the moment):


(itb="In the Black", river="Down by the Riverside", cauldron="Volta 2")

I can confirm the exporters producing -NaN for the cylinder patch generated from a 1x1x1 brush.

In commit e7bf1707e I changed the tesselation code to catch degenerate (0,0,0) normals. The model output isn't much better now, but at least the .ASE syntax is now free of the NaNs when exporting these patches.
