Module text_area 

TextArea — a multiline text editor.

Built for W5 of the Window Resize Test (egui’s “↔ resizable with TextEdit”) — a widget that fills its available area and lets the user edit a paragraph of text across many wrapped visual lines. Shares the underlying TextEditState with TextField so the same keyboard shortcuts / undo semantics are in reach later.

Scope (Stage 4)

Covers the behaviour W5 actually needs and what a mobile user would expect from an editable paragraph:

• word-wrap to the widget’s inner width;
• typing / backspace / delete / Enter produce visible edits;
• arrow keys navigate by char or visual line;
• click positions cursor; drag selects;
• cursor blink with focus state;
• copy / cut / paste via the standard clipboard shortcuts.

Deferred (known gaps, filed for Stage 5 polish):

• word-boundary jumps (Ctrl+arrows) across wrapped visual lines;
• undo / redo;
• input-method composition;
• BiDi and RTL layout.
