At z16 and below, tagged points are rendered with a small
dot in the center. At z17 and above, they are rendered with
a maki icon.
See the test rendering page for examples.
Fixes#381.
Can't unconditionally delete the node; it may be a member
of other ways.
I didn't preserve the behavior of dragging a midpoint to
an adjacent node being a no-op. In general we don't try to
eliminate compound operations whose net result is a no-op;
I don't think it's important to do so for this special case.
The degenerate case of connecting the endpoints of a two-vertex
line now results in a point. This is what naturally resulted
from the code, and seems ok.
Fixes#983.

During line and area rendering, fix up such ways so that they are
rendered as if the tags were on the relation instead.

This yields a 10x paint performance increase at
#map=18.88/38.85208/-76.72632, as measured with
Chrome Canary's "Continuous Page Repainting" mode.
Fixes#885.
Due to differenced redraw, midpoint.ways was getting stale,
so sometimes dragging a midpoint didn't add the new node to
all ways. Better to calculate participating ways when needed.
This also simplifies the code for adding a midpoint via double
click. It does make filtering midpoints on redraw a bit more
expensive, but a cursory profile didn't show it being a problem.
Fixes#763.
When recalculating parent ways/relations during rebase, a
graph should not add modified or deleted entities as parents.
Such entities will already be correctly marked as parents or
not.
Graph had the correct behavior for deleted entities, but not for
modified entities. This had the effect that if you split a way
that was partially off screen, and then panned so that the way was
re-retrieved, Graph#rebase would mistakenly add back the original
way as a parent of all the nodes that were split into the new
section, making them appear as shared.
Fixes#751.
