Zoom a view?

[neuronet]

Hmm... how exactly would this "zooming" work? Should all the text remain the same size ("not changing font size") or should the text grow with its quality worsened (one pixel of each glyph gets scaled to e.g. 4 pixels). Could you provide a mockup image of what you want?

I want the underlying font size to stay the same for printing or saving to PDF, but I want its appearance on the screen to change with some kind of interaction, such as a spinbox. I want high quality at higher magnification (so not like zooming an image where things get pixellated). Kind of like the following (except the one that appears bigger magnification should read 120%):

Open Office and MS Word both have this capacity. That is, there is a scrollbar at the bottom right that scales the appearance of the text (its size on the screen), but the underlying font size (point size) stays the same (e.g., for printing or saving the document). The quality is fine at high magnification. I was hoping for something like that with my tree view.
