Re: mobile-ACTION-33: Add "measured on the screen" and that it applies when that control is trhe only way to do something to 2.5.4 touch target size

Interesting but you can’t have this as an author guidelines —  since they have no ideas what size their buttons will have when measured on screen  —   they have no idea of the size of the screen or its resolution.

This increases the touch target size for all users and benefits people with dexterity impairments. It also reduces the number of redundant focus targets, which benefits people using screen readers and keyboard/switch control.
