Looks like when using PolygonOffsetEXT() mesa will multiply the bias value by
_DepthMaxF to set offset units (hence the same as calling PolygonOffset(). But
the get will just return offset units instead of bias instead.
I guess to really support that correctly we'd need to store bias separately.
After all _DepthMaxF of the bound draw buffer could change.
I don't know though if anyone is interested in that or we should just drop
