  Deprecate `intangible' and `point-entered' properties

The change was documented in a NEWS entry:

** Obsolete text properties `intangible', `point-entered', and `point-left'.
Replaced by properties `cursor-intangible' and `cursor-sensor-functions',
implemented by the new `cursor-intangible-mode' and
`cursor-sensor-mode' minor modes.
