In-progress strokes are invisible when the camera is panned too far from the origin.

[patowen]

Describe the bug
In-progress strokes are invisible when the camera is panned too far from the origin. I believe the root-cause is related to frustum culling (See additional context).

To Reproduce
Steps to reproduce the behavior:

1. Zoom out
2. Zoom in elsewhere
3. Draw a stroke
4. See that the in-progress stroke is invisible until you release the mouse (or you've passed POINTS_CHUNK_THRESHOLD)

Expected behavior
The in-progress stroke is visible no matter where the camera is.

Additional context
I believe the root cause is bevyengine/bevy#4294. I was able to resolve this locally by editing make_chalk to add the NoFrustumCulling component to in-progress strokes.

Thanks for reporting this issue and a possible solution. I'll try this.

I have a branch for my personal use (https://github.com/patowen/lavagna/tree/my-preferred-fixes) that contains fixes for some of the issues I've reported (along with unrelated changes based on my personal preference of using stable rust). I'm not really in a position where I'll have time to be a contributor for this project, but I have no qualms against you referencing or using the code I wrote there if/when you decide to work on this.

That being said, please let me know if you would like me to try to polish up some of these fixes and write a PR. This applies to #16 as well.

Hey! Thanks for your contribution! I see lyon bug is still there. So, until they have a fix, this workaround can be a solution.

If understand correctly, your branch fixes two bugs, #16 and #28, right? Can you create two separate PRs? Thanks

[patowen]

Sure! I'll try to polish anything up that needs polishing (especially given that the math in triggers_lyon_bug absolutely needs an explanation) and file a PR when I have time, hopefully soon.
