const hasWordWrap: boolean = (editor as vscode.TextEditor).options.wordWrap;

Add ability to detect if the current editor has word wrap turned on. Otherwise editor.setDecoration() is broken by putting items at the end of the wrapped line, instead of at the end of the first line. Example extension.

Example code:
const hasWordWrap: boolean = (editor as vscode.TextEditor).options.wordWrap;

Semi-related:
Add wordwrap indicator
Add support for language-aware word wrap

Unfortunately, checking the configuration isn't reliable in detection due to possible user changes in the current editor.
