vector3d scalar operator/ and operator/= no longer multiply by the inverse but use the expected division.

That was a bad case of premature optimization.
Multiplication is indeed faster, but when working with floats this can introduce some rather unexpected inaccuracies.
Like x/x suddenly no longer being 1.0 (something guaranteed by division). 
If someone really needs this back, then please add some new function which makes it clear we don't just have a typical division here.

--------------------------
Changes in 1.9 (not yet released)
- vector3d scalar operator/ and operator/= no longer multiply by the inverse but use the expected division.
Costs some speed, but fixes floating point troubles caused by this optimization (like x/x no longer being 1.0).
- Bugfix: XML reader dropped last character in strings if there was a special character replacement for the second-last character.
- Avoid allocating more than 16k on stack in OCT loader. Also avoid potential heap overwrites in there.
- obj file loader now allows using mtl files with spaces in the filename.
