Instead of "peeling off" my project, which is hundreds of files and a 
lot of code, i tried to reproduce it in a small test case emulating the 
matrix operations i was suspecting of. I didn't succeed though.

I will try again when i come back from some holidays. I don't explicitly 
use "inline" anywhere though. I guess the compiler does some inlining 
anyway. Maybe if i can disable it, i can see if anything changes.

I do "return this" however in some struct methods, for example:

	Transform opMulAssign( const Transform t )
	{
		m_origin += m_basis * t.m_origin;
		m_basis *= t.m_basis;
		m_type |= t.m_type;
		return this;
	}

and others. But even if "this" is a reference like Lars pointed out, the 
method should return a copy of the struct by value, right?
