If it is a toolkit-level feature that is needed desktop-wide, it needs to
be implemented in the toolkit proper, not added through the backdoor via a
module. I know that this will require some rearchitecting and may not be
super-easy, but I still believe that this is the right way forward.

The context is that visual-impaired users need magnification of the<br>
desktop. Changing font sizes / dpi etc. have their limit, at some point<br>
we need to just have a zoomed view of a piece of the screen. Currently<br>
compiz&#39; ezoom takes the piece of the screen, and magnify it to show it<=
br>
on the screen, with obviously awful pixelization effects.<br>
<br>
Our idea was very similar to gtk-vector-screenshot : instead of taking<br>
the output as it is displayed on the screen, get a module loaded within<br>
the application, with which ezoom can discuss to make the application<br>
produce a magnified rendering of its window, which ezoom can then show<br>
in the magnification glass, thus getting perfect zoom.<br>
<br>
Without module loading, I don&#39;t know how to implement it :) Or perhaps<=
