Yes, after I wrote that it hit me: font hinting would qualify as automatic pixel fitting. I was thinking about something more elaborate, like an algorithm that takes distances between neighboring elements, proportions and other factors into account (and which can be tuned to include/exclude factors). An example "smart" rule would be: If a group of elements are aligned, the same size and the same distance, they must remain aligned, the same size and the same distance after the processing Ideally it would be a plugin for a vector graphics application which could then allow the designer to add finishing touches to the places where the algorithm got it wrong.
