Pointer target size

Hi everyone,

We discussed pointer-target-spacing yesterday, and whilst there was a general wish to carry on with it, we needed a new version to account for some of the comments.

I've gathered a couple of suggestions together to form this version:

For each target, the horizontal and vertical distance between the center of the target and the closest edge of the nearest target is at least 12 CSS pixels except when:

  *   Inline: The target is in a sentence or block of text;
  *   User Agent Control: The size of the target is determined by the user agent and is not modified by the author;
  *   Essential: A particular presentation of the target is essential to the information being conveyed.

Note: The User Agent Control exception would not apply as soon as styling properties such as font size - and in the case of mobile/tablet browsers, viewport meta - has been modified by the author

(Google doc version<https://docs.google.com/document/d/1_EHFVE-p4jEtKFa2jMEUruSvu6iv-Vt7UxRW9SrHTCQ/edit?usp=sharing>)

Don't panic about the "12px" bit, that is the same as 24px wide/tall but if you measure from the center then you half it. It was a suggestion from Jeff Witt in #1444<https://github.com/w3c/wcag/issues/1444> that should prevent the shared space aspect.

CCing Wilco to make sure the testing perspective is considered for this approach.

There are other comments to deal with, but does this seem like a good basis to continue?

Kind regards,

-Alastair
