Finalize v2 Default Visual Style

[tig]

I'd like apps built with V2 to be visually distinct from v1. Right now, there are some subtle differences. I'd like this Issue to drive discussion on what we want the default look & feel to be.

Here's my current vision:

Colors

So-far:

• TrueColor is default which makes apps look more vibrant (Add TrueColor support to CursesDriver #2798 still needs to be done)

What's needed:

I really hope we can figure out these issues for V2 beta. They will be "Right" and will drive obvious visual distinction:

• Colors: Update Color System (TrueColor, Blink, Underline, etc...) for v2 (Master Issue) #457
• Colors: ColorSchemes refactor - Should honor terminal color settings etc... #2381

We will then need to pick great default colorschemes.

View Adornments

So-far:

• LineCanvas & Adornments enables more effective screen real estate management.
• Default glyphs for Button/Checkbox etc... (still needs work)

What's needed:

• Decide on default border styles for Window, FrameView, MessageBox, Dialog, etc...
• Decide on final Title layout (1-3 rows, left, center?)
• Enable Close/Quit/Collapse/Expand buttons on Border #2814
• Add mouse/keyboard resizing of views #2537

Styling

What's needed

• Shadow
  • Button.ShadowStyle = ShadowStyle.Opaque should be default.
  • Only overlapped Views should get ShadowStyle.Transparent
• Button alignment in MessageBox, Dialog, and Wizard
  • Default should be Center
  • MessageBox should be Center
  • Dialog should be End
  • Wizard should be End | IgnoreFirst
• Menu border or no-border?

Views

So-Far

• FileDialog is radically different
• Slider, ColorPicker are new

What are other's thoughts?

Good goals.

I'll more specifically sit down to think about the specifics of this issue and chime in with suggestions after some of my pipeline clears.
