Onyx Boox handwriting optimisation for Saber

[ZweckMa]

It would be amazing to be able to use Saber on Onyx Boox Tablets.
I managed to get handwriting support for Squid, wich is not supported by Onyx themselfs.

Has someone some idea what a "drawViewKey" with Saber might be?

just want to re-up this, I think there either is or was previously a branch of the software with Onyx SDK support built in. this would be a massive boost for Boox users.
