## Summary of the Pull Request This PR adds full support for the `DECSCNM` reverse screen mode in the Windows Terminal to align with the implementation in conhost. ## References * The conhost implementation of `DECSCNM` was in PR #3817. * WT originally inherited that functionality via the colors being passed through, but that behaviour was lost in PR #6506. ## PR Checklist * [x] Closes #6622 * [x] CLA signed. * [ ] Tests added/passed * [ ] Documentation updated. If checked, please file a pull request on [our docs repo](https://github.com/MicrosoftDocs/terminal) and link it here: #xxx * [ ] Schema updated. * [x] I've discussed this with core contributors already. If not checked, I'm ready to accept this work might be rejected in favor of a different grand plan. Issue number where discussion took place: #6622 ## Detailed Description of the Pull Request / Additional comments The `AdaptDispatch::SetScreenMode` now checks if it's in conpty mode and simply returns false to force a pass-through of the mode change. And the `TerminalDispatch` now has its own `SetScreenMode` implementation that tracks any changes to the reversed state, and triggers a redraw in the renderer. To make the renderer work, we just needed to update the `GetForegroundColor` and `GetBackgroundColor` methods of the terminal's `IRenderData` implementation to check the reversed state, and switch the colors being calculated, the same way the `LookupForegroundColor` and `LookupBackgroundColor` methods work in the conhost `Settings` class. ## Validation Steps Performed I've manually tested the `DECSCNM` functionality for Windows Terminal in Vttest, and also with some of my own test scripts.
