One thing he was struggling from time to time was applying multiple transformations to an element. When rotating an object the coordinate plane rotates with it which means dragging no longer works as one might expect (e.g. right becomes up). Raphaël’s creator Dmitri Baranovskiy indicated that is the correct behavior.
He started to work out a solution and released it as a plugin. It supports snap-to-grid dragging, scaling and rotating and handles sets. Like Raphaël itself, the plugin is licensed under the MIT license.
