Selection: tests check mesh lines in drag outlines; docs list the changed cases

The mesh tests now count each feedback path's subpaths, so a mesh that
drew its boundary instead of its mesh lines fails them. The progress-doc
lines name the Pathfinder, mesh and symbol instance outlines and the
limit's count of evaluated objects.

   - Dialogs move by dragging their heading (the band down from the top edge, as a title bar), stay on screen and keep where they were moved for the session; the form dialogs' choices are dropdowns (Offset Path's Joins, Average's and Shear's and Reflect's axis), and Offset Path lists Offset, Joins, Miter Limit and previews (#423).
   - Dialogs open with their first field focused and its value selected: type a value and press Enter (Move, Rotate, Scale…). A dialog opened from a menu takes the keyboard focus every time it opens, not only the first (#1367), and one whose first field starts greyed out (Blend Options on Smooth Color, Layers Panel Options) gives the focus to that field once it is enabled (#1395). Number fields in panels, the Control bar and dialogs (preferences too) step with Up/Down, or with the mouse wheel over the focused field (#485: a notch a step; the panel under it then stays put, and an unfocused field leaves the wheel to scrolling) (Shift: ten, Ctrl/Cmd: a tenth of their unit), applied at once.
   - While Alt (Option on macOS) is held, the Flare Tool Options' Cancel button reads Reset, which puts every option back to the Flare tool's default and leaves the dialog open (`ui.dialogReset`).
