1//! Shader methods that coordinate across both background and cursor shaders.

3//! These operations apply uniformly to whichever renderers are currently active:
4//! mouse input forwarding, key press timing, cursor state, progress bar state,
5//! cursor shader config updates, and animation pause/resume.
