Of course it would be possible to work around this in other
ways, or hack-fix it in Evas (e. g., publishing the output/
viewport ratio as a global variable and using it to scale
borders in evas_object_image as I did - yuck!). Yet I don't
know what the "proper" solution would be really... Probably
the objects need some kind of information about the output
resolution. We've got a similar problem with fonts in this
Regard (fixed dpi).
I think the scaling feature would be really nice thing to have
in evas. Here, I'm using this to show a GUI that normally runs
on an embedded device (small display) on a PC for beamer
presentations. It's very neat if you can scale the whole thing
to full-screen that easily.
