Deprecate PolygonOffsetFactor and PolygonOffsetDirection in SMaterial.
Replace it by PolygonOffsetDepthBias and PolygonOffsetSlopeScale.
Old values still work for now (as well as they did), but will be removed after Irrlicht 1.9.
The old implementation was based a lot on the way Direct3D8 had worked.
- We only had values -1 and 1 for the slope bias before, but sometimes other values are necessary.
- An int value for PolygonOffsetFactor couldn't worked for Direct3D9 which (unlike D3D8) uses a value range of -1 to 1.
Thx @ Criss and devsh for implementing some code which showed that different slope scaling is sometimes needed.

- Allow difference of 1 ULP in fast_atof tests (as that is still correct). Note that this only fixes part of the fast_atof test, the whole tests still fails on 64-bit because test_strtol still fails (that looks more like a real bug).
