Types
Functions
- init
It's expected to call this when
selfisundefined- textRunCreateEmpty
Creates an empty text run
Constants
- word_breaks
This is used for word selection - 2 clicks and ctrl+left/right - everything
Variables
- defaults
When break_lines is true, you can't get both a min width and min height,
