CJK漢字Chinese Handwriting-How to get Tegaki-Zinnia on Ibus?

I'm new to Mubuntu, but not to MATE, if hardly expert. One thing I noticed is that in the trend toward Input Method Editor named FCITX, that IBUS is not apparent as an option. I have ibus working on my DE fine, but one of the holy grails of CJK text input I have not found is how to get handwriting with Tegaki (with or without Zinnia?) working. The documentation on site is poor, at least to one who is no linux expert. The ibus addon is supposed to work, but I've never yet been able to get the Tegaki window to boot. As far as I can tell the project is moribund.

What options for handwriting CJK (Chinese, Japanese, Korean) are there which work under MATE? I'm comfy with ibus, but would switch to fcitx if it could do text recognition. I've looked into it a bit, but found naught. Has anyone gotten something to work with Rime under ibus or fcitx?

My system is a homebrew Frankenlaptop driving an Intel Celeron N2840. It has a touchpad, which would be nice to write on.

I hope some of this was lucid. Thanks!
