Use the `blf` module to accurately wrap the text for Blender versions v3.0+

[Pherakki]

Maintain a dictionary of characters and widths. When a new textwrap is encountered, create a set of characters from the input text. For each character not in the lookup table, measure the width with blf.dimensions(font_id, character) and record it in the table. Then, perform the text wrapping by adding words until the size would exceed the wrapping width and inserting newlines where required (how to deal with text without spaces?).

This is probably unnecessary...
