56d73ceb21 Dynamic blocks: show a distance's grip only at an end an action follows, and the grips of parameters a visibility state lists (#1090)
* Dynamic blocks: a distance's grip shows only at an end an action follows

A linear parameter's grip at an end no action is attached to moves nothing,
and AutoCAD doesn't show it on the reference: a stretch that follows only the
end's change (EndXDelta, EndYDelta) leaves the base without a grip, and the
other way round. A connection to the distance itself follows both ends, as
does a distance measured from its midpoint; a parameter no action is attached
to keeps the grips the block gives it. (A block saved with one grip has no
base grip at all, which was already honoured.)

* Dynamic blocks: a visibility state that lists a parameter shows its grips

AutoCAD shows a parameter's grips in a visibility state that lists the
parameter, though the state doesn't list the grips themselves (a label block's
Label state lists Position1 and Distance2 but not their grips, and AutoCAD
shows the square and the arrow). A grip now shows when the state lists it or
its parameter.
