    Aesthetically, the XPM icons may be serviceable for a fallback but they 
    aren't "good enough" when the other programs on your desktop are using 
    PNG or SVG icons.

Why do you think XPM icons are not good enough?
What is better about the PNG or SVG icons?

    I can understand that SVG:s are superior when scaling of course.

Does Emacs do scaling of toolbar icons?
If so, when, and why is it important?

    You said it.

I don't understand this -- what are "alpha channels"?  Maybe I
understand "anti-aliasing to the background", but the background for
the toolbar is trivial, right?

Can someone explain what different this makes
_for the toolbar_, and when and why?
