* Include just one 180x180px touch icon`.
Over time as Apple released different size displays for their
devices, the requirements¹ for the size of the touch icon have
changed quite a bit:
* 57×57px – iPhone with @1x display and iPod Touch
* 72×72px – iPad and iPad mini with @1x display running iOS ≤ 6
* 76×76px – iPad and iPad mini with @1x display running iOS ≥ 7
* 114×114px – iPhone with @2x display running iOS ≤ 6
* 120×120px – iPhone with @2x and @3x display running iOS ≥ 7
* 144×144px – iPad and iPad mini with @2x display running iOS ≤ 6
* 152×152px – iPad and iPad mini with @2x display running iOS 7
* 180×180px – iPad and iPad mini with @2x display running iOS 8+
However, most iOS users will be on the latest 2 versions² of iOS
and using newer devices, so nowadays, one 180x180px touch icon is
enough.
Also, if needed, the icon will be automatically³ downscaled by
Safari, and the result of the scaling is generally ok.
* Remove unneeded `sizes` attribute.
When using only one touch icon there is no need to use the `sizes`
attribute.
