With the recent developments on the X.org side you'll hopefully get zooming of 
apps rather soon, but with Qt 4 you'll also get the zooming in widgets.

You's still have to do some work in the view, but once the apps use Qt4, they 
will get quite a bit of it for free. The problem with zooming in the painter 
is that the results will usually get somewhat blurry, which for an html view 
can be a problem. But I guess that's something one could try out.
