Shapes and images can now be resized, rotated, and skewed directly on the canvas, not just moved. Both share one small transform struct (rotation, then skew, then scale, anchored on a movable pivot) and one handle widget, so a corner drag, an edge skew, or grabbing the rotate handle behaves the same way and runs through the same matrix math everywhere, instead of every item type reinventing its own. Shapes also gained a proper pen tool (bezier paths, corner/smooth/ symmetric nodes), arc support, and mirroring. Images gained non-destructive cropping and colour-keyed transparency, both remember their own settings, so reopening the dialog picks up where you left off instead of starting over. Properties dialogs for both were extended to match (position, size, angle, skew), with undo/redo wired through for every handle drag. Old XML files can read easily as the transformation is only added if needed and the old syntax is still used and understood if it is not needed.
