Addressing #1179 (comment)
The points are addressed in a new section, "Scope and applicability"
Also updating the second paragraph in section "Intent of Pointer Target Spacing" to make it easier to understand (or so I hope).

Took out the bit that the SC applies to the spacing between native elements (I think it that is clear), but addressing @JAWS-test's comments, added an exception for the spacing of targets _inside_ unstyled native elements (i.e. where the vertical spacing of options in a select is determined by the default browser behaviour).

Following comments by @patrickhlauke I removed mention of touch in two places.

Added a third example (row of buttons with sufficient spacing above and below).
Edited the figcation / legend of thee image with the three differnet positionings of the magnify icon over a profile image, reduced length of the alt attribute.

@patrickhlauke Changed criteria to criterion where needed
Changed some of the figaption text to make them easier to understand
Changed an odd sentence above the profile images /maginfication icons illustiration
Changed the paragraph above h2 Benefits (pointing out the benefits of general adaptability of size/spacing)
Added a third example in second position (row of buttons where enough vertical spacing is present to meet SC)

I improved the ficaption legends of the illustration, some were hard to understand.
I improved the image legends / figcaption texts, and removed the heading Scope and applicability, would have needed a further subheading to separate what are essentialy examples with illustrations. It is odd that there is an actual section Examples further down whithout illustrations, but I do not want to carry through a complete overhaul of the Understanding page at this point. I think it would generally be benefitial to have more subheadings in the longier understanding pages, not just Intent / Benefits / examples, but I am not sure how flexible we are in this respect...

Changed to "or must be placed at the edge"
Accepted "to make sure that there is sufficient adjacent spacing in each dimension"
Changed to "and a magnifying glass"
Changed "excempted" -> exempted

Slightly changed wording:  "Having targets with sufficient target spacing can help all users who may have difficulty in confidently targeting or operating small controls. Users who benefit include, but are not limited to:"

Updated name to "Using min-height and min-width to ensure sufficient target spacing"
