* Typed `master` to each `__init__()`. * Having to `# type: ignore` the base class for the classes which are "tk on darwin, else ttk" as this 'dynamic' type confuses mypy. See the comment on `class Frame` for a suggested proper fix, which will be more work.

Custom `ttk.Notebook` to fix various display issues.

Hacks to fix various display issues with notebooks and their child widgets on
|
|
OSX and Windows.
|
|
|
|
- Windows: page background should be White, not SystemButtonFace
|
|
- OSX: page background should be a darker gray than systemWindowBody
|
|
selected tab foreground should be White when the window is active
|
|
|
|
Entire file may be imported by plugins.
