So this is where it gets complicated:
The source code looks roughly like this:
Matrix Ellipse::GetMatrix()
{
... some inlined function ...
Matrix matrix;
... some inline function ...
return matrix;
}
So we need to be tracking it because the local variable matrix uses the storage of the return argument.
