layout.touchTargets

Grows the toolbar, navigation bar, search bar, the Text options bar's selects, and the Edit Text options bar's selects, Delete and Done to 44px hit areas on a coarse pointer, and shows the current thumbnail's page actions without a hover. Set it to false to keep those mouse-sized on a touch device; the pointer is still reported as coarse, so the on-page handles, the options bars' chips, panels and dialogs keep their touch sizes.
