Currently, when laying out nodes under any settings, the TreeLayoutAlgorithm determines node size and layout based on a pre-determined fixed canvas size. It would be very helpful to have tree layout determine ideal size given ideal node size and separation and determine canvas size from that.

Workaround:

Override TreeLayout with:

					protected void preLayoutAlgorithm(InternalNode[] entitiesToLayout,
							InternalRelationship[] relationshipsToConsider, double x, double y, double width,
							double height) {
						int maxDepth = contentProvider.getMaxDepth();
						int attributeCount = contentProvider.getAttributeCount();
						super.preLayoutAlgorithm(entitiesToLayout, relationshipsToConsider, x, y,
								attributeCount * m, [maxDepth] * n);
					}

But it is difficult to determine max Depth and results are inconsistent.
