Terminal: Feature request: Background image for tab, not per split pane

[maciejmiara]

Description of the new feature/enhancement

Currently, when I have a tab opened in terminal, it uses background image of specific profile. If I add more split panes from the same profile or from different ones, background image tries to fit pane for specific profile.

So it looks like this for single pane in tab:

And like this for multiple panes in tab:

I'd like to have single background image for tab, even if it has multiple panes (image would be just "cut" by panes borders). So I'd like to have only one background image like in first screenshot, but still use many panes, like in second.

For this scenario, background images of specific profiles would be ignored or only background image of first pane opened in tab would be taken into consideration and shown.

Lots of other configuration options which control how terminal looks like could be also configurable per tab.

This would make a neat extension idea. I've tagged it up as such and added it to our mega extensions list, thanks!

I'd love this, even if it were in core.

@DHowett Do you think this idea could make it through to the core?
If yes, I can start thinking, how it should work.
It'd be easy to have only one "tab profile", which would simply overwrite view-related profiles settings for all tabs if enabled. More hardcore scenario is having several "tab profiles" and having possibility to switch between them somehow (every tab can use different profile).

Extensions system will probably start working in two years perspective, cause there are some Windows changes required.

@maciejmiara The solution to this could be made much simpler from a user's point of view: give the user another option for backgroundImageStretchMode, or another setting entirely, that makes the background image always align to the tab instead of the pane. The pane will then just show the portion of that tab aligned background image inside its boundaries. This way, if all panes are of the same profile, they will all show the full background image together. And if one pane is of a different profile, it will show a portion of its background image instead of the full one (assuming that profile's background image is also configured like that).

It's also possible to have the background of the profile that is _in focus_ be the tab background. Just throwing an idea here. Either way, I would love being able to toggle 'per tab'/'per pane' background image behavior.
