[BUG] if vcam is on a layer with opacity, nothing on it renders

[BaronAWC]

Describe the bug
if you set the opacity to anything less than 1 and have a vcam on that layer, the elements on that layer do not show up. other layers will show up though.

To reproduce
Steps to reproduce the behavior:

1. add a vcam with black bars enabled and another object to the canvas
2. set the opacity to something less than 1
3. play the project

Expected behavior
elements on the transparent layer show up properly

Screenshots
If applicable, add screenshots to help explain your problem.

Editor version
should be only on candlestick, since that's the one with layer opacity

Do you have a suggested solution to this issue? (ex. has another program fixed this bug a certain way? Are you familiar with where in the code base someone would need to fix this issue?)
if you have giant objects that have opacity, wick doesn't really like it and so it just doesn't render at all. the wick vcam is giant with the black bars so that's why it fails to render. if you edit the black bar frame to have way less stuff, it will render as expected.

though, the black bars will be transparent too, which is predictable but not desirable. not sure if there's even a fix for this. maybe you can just prohibit the vcam from being on a layer with transparency.

Another weird thing is by setting the vcam animation to "Single Frame" and frame 1, it clears the issue for some reason

Edit: Yeah, this is a problem with paper.js paperjs/paper.js#2001

looking at it now, this bug of stuff disappearing is not limited to the opacity of the layer or even previewing the project. lowering the opacity of the vcam clip or the black bars inside the clip will trigger the bug.

interestingly, if you go into the clip and decrease the opacity of one of the black bars, you can zoom in and out in the project and find the point where paper refuses to render it (and cause a lag spike).

other than making the bars smaller or dynamically resizing the bars with code, i don't think there's much of a fix. (not that anyone should be putting the vcam on a transparent layer anyway...)
