New Rendering Engine with more Comfort and Performance

This page covers new features and modifications in version 3.0, compared to the previous release V2.1.

New rendering engine
The rendering engine which is responsible for all drawing operations has been completely reimplemented in version 3.0. The engine is the foundation of many new features like color icons, graph export, and so on.
More comfort
The new rendering engine offers more comfort for the user. For example, edges are no longer displayed in an abstract way when using fine-tuning, so their style and arrow is always kept visible if the parent or child node is moved with the mouse. Tooltips appearing automatically on graph nodes and edges (see below) are another benefit. Dummy nodes which are at the bends of edges (where the horizontal levels of nodes are crossed) are now highlighted automatically when they are reached by the mouse pointer which is a great help when you are adjusting the position of edges.
Improved efficiency and scalability
With the new rendering engine, memory consumption has been reduced significantly, especially for large graphs and when using uDraw(Graph) for a longer time. A couple of serious memory leaks have been eliminated, so you will see much better performance and stability. Pixmap caching, available in previous releases, is no longer necessary due to the new advanced drawing algorithms.
