bug#39246: 26.3; more documentation needed for Pointer Shape

[ynyaaa]

I checked pointer shapes on my Windows PC.
    SYMBOL    REAL-SHAPE
    text      Like a serif glyph of 'I'
    arrow     north-west arrow
    hand      up pointing hand
    vdrag     north-west arrow(same as 'arrow)
    hdrag     right-left arrow
    nhdrag    up-down arrow
    modeline  north-west arrow(same as 'arrow)
    hourglass rotating ring
'text shape is described in info (elisp)Pointer Shape.
'arrow, 'hand and 'hdrag shapes are predictable.
'vdrag, 'modeline, 'hourglass and 'nhdrag shapes are not predictable.
They need to be described more in info.

Especially, 'nhdrag shape is not referred to in info.
It is referred to in help C-h v void-text-area-pointer.

'hand shape is used for the default shape of mouse-sensitive areas.
It should be described in info (elisp)Special Properties and
(elisp)Image Descriptors.

'hand shape is different from the system pointer for link selection.
