[Inkscape-devel] NEW: "transform with object" toggle buttons

* The preferences that control scaling of stroke widths and rectangle corners, as well as transforming gradient and pattern fills with the object, are now represented by four toggle buttons in the selector's controls panel for easy access.

* Gradients no longer behave weird when a path with gradient fill is transformed. Now gradients either transform with the object or remain unmoved, depending on the user setting (toggle button in selector controls). This setting affects grouped objects too.
