Moving the sliders now automatically and immediately updates the preview image.
Note: For slow and complex styles the update may be visible only when the slider "stops", because moving  the slider continuously may not give the computer's RAM memory enough time to calculate the result before moving on to the next calculated image view.

The Property Editor sliders are no longer limited to the range defined in the style. The recommended range is now highlighted (out of respect to the style author's intent of the style), but any values accepted by the embedded filter can still be set to transform the style into something else or to fit the style to smaller/larger images.

"Reset properties" button in the Property Editor: usefull when the properties have been modified too much. Clicking the Reset properties button brings back the original default values of the style/filter.
