Dynamic Node sizing and/or text label sizing

[orchetect]

Description

Long connector labels are crowded if the string length is substantial.

Proposed Solution

• Add some constraints to the text labels to allow them to wrap and not overlap/collide
• Provision for the Node to size itself to its contents dynamically, perhaps with some settable min/max size limits.

Describe Alternatives You've Considered

No alternatives are possible aside from manual truncation of the string prior to assigning it to the Node's input/output labels.

I was hoping to draw the text in a rect so it will be elided when drawn. Unfortunately, there doesn't seem to be a way of specifying text alignment when rendering inside a rectangle (so the output label can't be aligned right):

I think it's also tricky to measure text.

Given all that, I think we should just expect clients to pass in elided node labels that work for their application, and file feature requests with Apple as necessary.
