V2 View cleanup

[tig]

As I progress on the v2 View redesign (#2360), I'm finding things in the View hierarchy that are hard to understand, overly complex, poorly named, overly exposed (publicly), and oddly tested.

Instead of fixing this in one massive PR that includes a massive redesign/rearchitecture, I'm going to be doing PRs like this one that fix them without significantly changing functionality.

This PR:

• Simplifies, clarifies, and better documents View initialization.
• Renames internal methods and property names to increase code clarity
• Hides (internal) and removes some formerly public members that are unlikely to be used - a lot having to do with sizing
