wanted to use the quadtransform nodes to rotate my bounds rectangle, but it seems it just gets scaled.
I am aware you cannot freely rotate a bounds rectangle, but this is a bit misleading, being able to use a transformSRT but rotation not working.
matrices can often do more than what a specific use case allows/makes sense. and as the 2d rectangle type is always axis aligned, this is the correct behavior. if you rotate the corners or a quad by 45°, the projection of the corners onto the coordinate axis will form a rectangle with an area of 0. So rotating axis-aligned rectangles is like scaling.
if you apply this matrix to a quad model, it will rotate normally.
