Closed shapes start where they twist least (unless the Blend tool
picked the anchors); dashes, miter limit, arrowhead scale and width
profiles interpolate (caps, joins and brushes switch halfway);
gradients with different stop counts resample to common stops; groups
with different member counts grow the extra members out of a point;
compound steps stay compound paths; type, symbol instances and images
interpolate their transforms, type its colours and sizes run by run.
New blends are knockout groups and the canvas draws them knocked out
as the exports do. Expand and Release keep the blend's name,
transparency, opacity mask and appearance, and Object > Expand expands
blends.
