Gallery example CPU usage

[oysstu]

Tried the gallery example with the spinner indeterminate enabled while idle, and also moving the slider connected to the progressindicator/spinner to see what CPU usage would be (percentages of a single core).

• C++ gallery example (winit-skia): 22% idle and 80-100% when moving slider
• Rust gallery example (winit-femtovg): 6% idle and 40% when moving slider
• Wasm online examples (firefox/chromium): 8% idle and 10% when moving slider

Is this in line with your expectations? With indeterminate turned off, C++/Rust falls to 0 CPU and wasm is around 3%.
