Summary0005868: Interactions rendering with polygonOffset
DescriptionRight now interactions rendering never enables polygonOffset.
Usually polygonOffset is applied to patch-surfaces which are exactly on a solid surface (mappers call such patches "decals").
However, if such surface has complicated material (for instance, has specularmap), then polygonOffset does not fix depth fighting.

A major example of this issue is stain01bwet material, which is used in Stain Lucia map.
It was used long time ago because its specular map did not work.
And when it started working, depth fighting happened.
Steps To Reproduce1) Uncomment "specularmap textures/decals/stain01b_s.tga" in
2) Run Saint Lucia and go to the statue.
3) Observe depth fighting on the floor as you move or rotate camera.

Note: most likely you should NOT commit the updated stain01bwet material even after this is fixed.
Leaving _black specular map results in proper appearance --- the one which was in TDM 2.00.
