Ferenc Arn 97d510531a Fix polar decomposition in 2D. 
When performing polar decomposition in 2D as B = R.S, where R is rotation (with determinant +1) and S is scaling, use the convention that reflections are absorbed into S through a reflection around y axis.
In 3D, this is done by using a reflection along all three axes, but since the dimensionality is even in 2D, one axis needs to be chosen.

Fixes Matrix32::get_rotation and Matrix32::get_scale (which weren't properly fixed in #7445).
