There seems to be no limit for how far you can zoom by scrolling the mouse-wheel. It would be nice if there was a way to limit the scale of the image to both a max and min value.

Instead of it languishing here.

The interpolation of scaled down images especially with text can be quite bad. A decent but still fast interpolation method would be appreciated.

The same image in the gimp viewport for reference:

And now in a gtk imageview:

In both cases the image is scaled to 80%

The vala-demo throws this line after opening an image:

(vala_demo:11177): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

This is not the case in the c-demo. So I guess there is something wrong with the vapi-file?

The wiki page of GtkImageView is talking about "zoom modes":

There are currently 3 zoom modes:
-GTK_IMAGE_VIEW_ZOOM_MODE_FIT: The minimum size of the widget is 1×1, the natural size the image's size. if the widget's allocation is smaller than the image's size, the image gets scalled to the allocation (i.e. we never scale it up).
-GTK_IMAGE_VIEW_ZOOM_MODE_ORIGINAL: Minimum size of the widget is the image's size. The image doesn't get scaled.
-GTK_IMAGE_VIEW_ZOOM_MODE_NONE: See question at the end

I can't find anything like this in the code. Was this scratched or is it still planed?

set_animation should take a scale factor
