And that is not what I am intendig. 
I wants the ability to let the screen show 
the same content independent of screeen resolution. 
I want bigger letters on a big monitor, 
not small letters on a high res monitor. 
In other words, I want the ability to show 
a document with the same "Image", 
only bigger on a big monitor, independent of resolution.

Contrary, some of these actions on the user-agent 
might be unnecessary if the document itself tells 
how it should be displayed.
