Detailed Description

Component state management using compact bitfield structure.

Stores all component state flags and properties in a single 16-bit bitfield for efficient memory usage and improved cache locality.

Each component property maintains two state flags:

needs_update: Indicates the property requires synchronization with the display
is_set: Tracks whether the property has been explicitly configured

The visible field stores both the update flags and the actual visibility state.
