theme.smallIconSize vs theme.iconSizes.small

[Kai Uwe Broulik]

Hi,

playing around with the new tasks widget I saw that it does not adapt to my 
small icon size setting which I have set higher because of my high-dpi screen.
Now it seems that icon sizes in Plasma theme are fixed in the theme. Is there 
some sort of dpi scaling mechanism or how can this be made future-proof?

I don't like using KIconLoader IconSize arbitrarily anywhere either but they 
are at least user-configurable. My dream would of course be a dpi-independent 
UI but how can we improve this situation without messing up people's layouts 
and code? Have the theme icon size based on 96 and scaling depending on screen 
DPI and/or font DPI? I've seen there's some units thing in Plasma that does 
such sort of magic.

Best,
Kai Uwe
