There is an updated pull request by mtboehlke against master on the void-packages repository

https://github.com/mtboehlke/void-packages idesk
https://github.com/void-linux/void-packages/pull/39550

idesk: update to 0.7.8.
Switching upstream to maintained fork at [https://github.com/neagix/idesk](https://github.com/neagix/idesk).
This seems to be a good choice for upstream: has tagged release and ChangeLog is being kept up to date.

The re-added SVG support seems to work okay, so I have enabled it here.
