Make sure the theta is correctly represented and incoming polygon is CW for shadow.
...
Now the theta = 0 should be on +x axis.
And cos(theta) should correctly represent x value.
Without this fix, the poly theta (from atan2) can be wrongly rotated 90 degrees.
Also, make sure the incoming polygon is CW for the shadow system.
This fix visual artifacts in recent regression for spot shadows.

Fix the missing spot shadow when DEBUG_SHADOW is turned on

In the current design, this error should be tolerated since the delta should
be small enough. So we should not return here.

transforming the polygon XY points (using the actual draw matrix) and
a separate one which respects correct 4x4 3d rotations and
translations for determining Z values.
