[vtkusers] Speed up cell allocation

[quadprob]

Hi,
My program is suffering from very noticeable start up times even though
rendering itself is quite smooth. From profiling I've learnt that what's
taking up most of the time is the vtkCell constructor calls. So what I'm
essentially looking for is to speed up something like this:

public static void main(String []args) {
	int numElems = 739872;
	vtkCell[] elems = new vtkCell[numElems];
		
	long startTime = System.nanoTime();
	for(int i = 0; i < numElems; ++i) {
		elems[i] = new vtkHexahedron();
	}
	long stopTime = System.nanoTime();
	System.out.printf("Took %dms\n", (stopTime-startTime)/1000000);
}

Do I have any options other than parallelizing the main loop?
