Test Description

Rotation about the origin is equivalent to the matrix [cos(a) sin(a) -sin(a) cos(a) 0 0], which has the effect of rotating the coordinate system axes by angle 'a'. The test overlays a group of black graphics elements with a 'rotate' transform specified on top of an identical group of red elements with the equivalent 'matrix' transform and vice versa.
