Full CPU/GPU usage even when paused (brawllib_rs)

[jagoly]

Right now, rukaidata will always re-draw the viewport, even if the animation is paused, and the camera and options have not changed. This means that cpu and gpu utilisation is very high whenever a subaction is open.

For me, using a laptop, this is pretty annoying since I have to always remember to switch to a different tab before alt-tabbing away from firefox. Often I forget and am only reminded when my legs start to get warm :(

I believe that it should be not too hard to change it so that the viewport only gets rendered when something has changed. I had a quick look into trying to do this myself, but for now at least it's beyond my extremely basic rust knowledge.

Thanks again for the tool!

Thanks for the report.

The rukaidata javascript renderer will be replaced by the brawllib renderer running over wasm soon. It's already accessible behind the --wasm flag,

So no point fixing the issue in the javascript renderer but the wasm renderer probably has the same issue.
The solution would be to only redraw when a https://docs.rs/winit/0.25.0/winit/event/enum.Event.html#variant.RedrawRequested is received
