* This class is used in many classes of rekonq to produce an image
* based on the site corresponding to the url passed as argument.
* It also cached the images to not retrieve them every time :)
*
* Heavily based on Graphics-Dojo WebSnap example (thanks!)
*
* We use this in the following rekonq classes:
* - TabBar class: to show a tab preview (given a page, you show WITHOUT saving an image)
* - NewTabPage class: to show the favorites page "preview" (given an url, you show AND save an image)
* - PreviewSelector class: to save new favorite selection (given a page, you show AND save an image)
