enum ANNOTATION_PERMISSION

An annotation permission enumeration for controlling annotation permissions. This enum is used in `getAnnotPermissions` callback defined in PDFViewer constructor option. Example:

var author = annot.getTitle();
switch(author){
case 'admin':
return Promise.resolve([ANNOTATION_PERMISSION.fully]); // The 'admin' has all permissions
case 'manager':
return Promise.resolve([ANNOTATION_PERMISSION.modifiable]); // The 'manager' has modify permissions
case 'normal-user':
return Promise.resolve([]); // means 'normal-user' has no permission
}
return undefined; // Do not control permissions on this annotation.
}
}
