Wired up the update of the UI without calling refresh view. Now the
iframe preview is not updated.
Using the distributeOptions facility to apply text-size changes to
preview. Upon "Save" this no longer works, so we need to overcome that
bug.
Created enactor for cursor-size that only affects the preview.
Removed the erroneous load event hook from preview frame on text size.
Created enactor for magnification that only affects the preview.
Magnifier actually scales the "container" member and uses
distributeOptions to pass these to preview. However, now all changes are
reflected to all container-enacted previews.
Set the transform origin to 0,0,0 for magnification scaling
transformation.
Tweaked a bit the steps and ranges of adjusters.
