Subject: [PATCH] workspaceThumbnail: Expose maxThumbnailScale as property

Some extensions want to modify the value of the MAX_THUMBNAIL_SCALE
constant. That is no longer possible, as exports are always read-only
from the outside.

Make this possible again by exposing the scale as a property on the
object itself, so extensions can override it.
