(re: #4271, #3636)
- better classification of "interesting" vertices
(include tagged, selected, or child of selected)
- now we can draw labels on selected lines again (revert #3636)
because the labels will avoid the vertices
- if debugging is on, draw a collision box for the mouse
(re: #3003 / #4602)
For now, drawHover is commented out. Still not sure what I will do with it.
This means that things flicker a bit when dragging, also connecting nodes
(and closing lines) does not currently work.
There was lot going on preventing the vertices from rendering while dragging.
1. `modeDragNode` needed a proper `selectedIDs()` function that works like other
modes.. Many other places in iD (including the vertex renderer) call `context.selectedIDs()`..
This means that `modeDragNode` needs a new function `restoreSelectedIDs()` to do what
`selectedIDs()` was previously doing (a place to store selectedIDs so that we
can reselect those entities after the user is done dragging a node in select mode)
2. Just so many things in svg/vertices.js
- siblingAndChildVertices was missing some things for points that we render
as vertices (points in wireframe, points with directions)
- the sibling vertices weren't being included in the `filter` function, so
would disappear when doing differenced/extent redraws
- probably some other things
Sometimes people tag all-way stop signs at the junction node,
othertimes people tag all-way stop signs at the stop sign location.
What we're doing here is:
- if `stop=all` tagged at the junction, show viewfield in all directions
- if `stop=all` tagged at the sign location, show viewfield according to `direction=` tag
Previously it was up to the caller to draw whatever they want into the
footer flash. With this change, uiFlash creates an icon and a text, so
the caller doesn't need to do as much work.
Between keyboard shortcuts screen and onscreen hover text, I think we have
the icons covered well enough and don't need to add it to the help. Having
it in help means that translators need to do double work.
