Wouldn't your request be better handled by integrating an overview map 
with rectangular outline?
I just feel that you attack the problem at the wrong place....

(BTW the biggest speedup for maps we can integrate is still to have an 
overview map for mapsource that is not empty - on GPS if you go lower 
than resolution 18 or 17 anyhow basemap is better suited than detailed 
map too.
Would it be so difficult to define in "options" file of style-file that 
the lowest resolution (actually a 2 resolution overview map would be 
even better) is not input into normal tile but put into overview map?)
