Setting minimum width for tabs in TabContainer

[neruthes]

I intend to enforce a constant width for all tabs. The current behavior is to shrink (adapting to text content) as much as possible to minimize total width. I could not find a way to make this happen in Godot documentation or online discussions. StyleBox does not have a minimum width feature and that looks legit; it appears that TabContainer should solve this on its own. Let me know if any solution is available now.

Minimum width technically still allows content that really needs more space to exceed the limit.

I think a better fit is to add something like a fixed_tab_width toggle. When enabled, make every tab the same width (as the widest width tab).

If we are to make things extendable enough to cover much more cases...

• Minimum width: Mandate the smallest allowed width.
• Maximum width: Mandate the largest allowed width.
• Opportunistically shrink: Shrink all tabs to the same smallest possible width, but not smaller than minimum width.
• Opportunistically enlarge: Enlarge all tabs to the same largest possible width, but not larger than respecting maximum width.
• Content overflow behavior: Visible, Hidden, or Ellipses.

I wrote a script NSTabsMgr for this.

Attach it to a stand-alone Node. Feed references of tab buttons and tab contents as 2 arrays. NSTabsMgr listens to button_up events and hides certain nodes according to which button is pressed.
