Avoid undefined behaviour in GTK animation frames

[JAicewizard]

Requestion an animation frame is and always has been undefined behaviour.
This is not documented ANYWHERE besides the brains of whoever coded this.
See https://gitlab.gnome.org/GNOME/gtk/-/issues/3703.

Before merging, someone else please confirm that this code works. I currently cannot compile druid (AGAIN!!!! FFS rust how is this even possible. How can it never just WORK).

This is copied straight out of my gtk4 code which did work.
To test you can try running the anim example, and also see if the text widget updates properly (both without moving your mouse, as that causes a new frame anyways).

Both examples are working fine.

sounds horrible 😬

I believe this only affects druid-shell because druid doesn't let you request animation frame when painting (at type level!)

CI is red due to new clippy lints (in 1.53)

I would love to know why. if you are bellow rustc 1.51 then it can solved by commenting out the const generic data impl for array

No!!! because we base the whole cycle druid lifecycle on GTK draw events, including update. This is the only real option, since there isnt many other events this could be put into.

no I tried all channels. I didnt have much time today, I will try to reinstall rust all together. That didnt fix things last time, but it might now 🤷

rebasing should solve the CI issues now

[JAicewizard]

CI seems fixed 👍

[JAicewizard]

welp, as github seems to have broken itself, CI fails. I tested the new code and works as before.

Thanks! Both animation and textbox examples are working
