Fix for fxShapeReplicator to honor rotation

fxShapeReplicator ignores the rotation of the area in which one wants to have the shapes. This is especially annoying if your replication area is long and narrow like mine in this example


This is because the feature was never implemented by Melv. The code below fixes that.

Open your fxShapeReplicator.cc file

In CreateShapes() find the code

// Find it a home ...
		do
		{
			// Get the Replicator Position.
			ShapePosition = getPosition();

			// Calculate a random offset
			HypX	= RandomGen.randF(mFieldData.mInnerRadiusX, mFieldData.mOuterRadiusX);
			HypY	= RandomGen.randF(mFieldData.mInnerRadiusY, mFieldData.mOuterRadiusY);
			Angle	= RandomGen.randF(0, M_2PI);

			// Calcualte the new position.
			ShapePosition.x += HypX * mCos(Angle);
			ShapePosition.y += HypY * mSin(Angle);

and replace with

// Find it a home ...
		do
		{
			// Calculate a random offset
			HypX	= RandomGen.randF(mFieldData.mInnerRadiusX, mFieldData.mOuterRadiusX);
			HypY	= RandomGen.randF(mFieldData.mInnerRadiusY, mFieldData.mOuterRadiusY);
			Angle	= RandomGen.randF(0, M_2PI);

			// Calcualte the new random position (in local space).
			Point3F RandomShapePosLocal;
			RandomShapePosLocal.x = HypX * mCos(Angle);
			RandomShapePosLocal.y = HypY * mSin(Angle);

			// Transform into world space coordinates
			Point3F shapePosWorld;
			MatrixF objToWorld = getRenderTransform();
			objToWorld.mulP(RandomShapePosLocal, &shapePosWorld);
                        ShapePosition = shapePosWorld;

Recompile and thats it
