描述

The fallback painting code should be changed to use timers. Right now it uses the idle loop, but this isn't ideal: it forces us to either write a bunch of special-case code for painting or else rate-limit the idle loop to avoid painting to often (this is the current state).

研究方向
Look into the X11 shell painting code in druid, specifically the fallback painting implementation that uses the idle loop. Investigate how timers are already used in other parts of druid's event loop (e.g., in the winit backend) and plan a refactor to replace the idle loop with a timer based approach. Examine any related comments or linked issues that might specify expected behavior or API preferences. Since there are no comments or PRs, the maintainer's intent is primarily described in the issue body.
