Text Input Control

[mdwigley]

Feature Description

This feature introduces a fully functional text input control that supports keyboard input, text selection, caret management, clipboard operations, and undo/redo functionality. It integrates with the existing rendering and layout framework, allowing intrinsic sizing, dynamic style application, and precise caret placement. The control is designed for developers to provide editable text fields in user interfaces with robust behavior and consistent visual styling.
