I like the idea. How would fractional scaling be handled though? If I'm
using a 1.25x scale (as I am right now), would it generate an @2x
thumbnail, store that, and scale it down for display? Or would it
generate an @1.25x scale thumbnail?

Hello,
I have been working on adding support for HiDpi thumbnails in KDE
frameworks. [1]
So I'd like to take the high road and update the specification [2]
The crust of my specification update proposal is as follows :
Thumbnails generated with high-dpi (usually using a scale factor of 2)
should be stored in folder using a suffix a @<scale-factor as int>x
suffix, i.e :
$XDG_CACHE_HOME/thumbnails/large@2x contains up to 512x512 thumbnails
with a scale factor of 2
$XDG_CACHE_HOME/thumbnails/normal@2x contains up to 256x256 thumbnails
with a scale factor of 2
An additional attribute Thumb::DevicePixelRatio might be added to store
the actual scale factor (as an int).
The @2x suffix is already used in breeze-icons to symbolize 2x scale
ratio resources. [3]
Once I have some traction with the proposal I will submit a merge
request [4].
