Bumps github.com/gdamore/tcell/v2 from 2.6.0 to 2.7.4.

Release notes

Sourced from github.com/gdamore/tcell/v2's releases.

Version 2.7.4 Bug Fix Release

This release fixes a problem with restoring cursor location properly on Windows.

It also includes a new stress test for your terminal (FPS monitor) contributed by @​Bios-Marcel

Version 2.7.3 Bug Fix Release

This release just updates the terminfo data using current data from Ubuntu 24.04 (Noble). It fixes a regression where we dropped some capabilities including StrikeThrough for some terminals.

Version 2.7.2 Improvement Release

This release does not add new APIs, but it does improve the functionality of tcell on Windows, and provides an "undocumented" feature for managing the alternate screen buffer.

• Windows uses VT mode output everywhere except on ConEmu (because VT output mode on ConEmu is borked for colors)
  • The TCELL_VTMODE environment variable can be set to "enable" or "disable" to force attempting to use (or not) this mode.
• Windows now uses the alternate screen buffer by default, and preserves the original screen content
• Use of the alternate screen can be disabled setting the TCELL_ALTSCREEN environment variable to "disable".
• If the alternate screen is disabled in that fashion, we will not clear the screen either. This is an experimental way to preserve the output from a tcell application on exit or suspend. Feedback on this would be appreciated.

The specific environment variables listed here are not considered part of the Tcell API, and their presence and meaning may change without notice at any time. Please consider them experimental and let us know whether these are useful or not.

Version 2.7.1 Bug Fix Release

This release fixes a few problems, and also adds a feature that was missing on Windows.

• Fix for disappearing wide (including emoji) characters on Windows (#621)
• Fix for wide characters causing scrolling when on bottom line on UNIX/Linux (#679)
• Fix for PollEvent returning nil on screen Suspend (regression) (#687)
• Fix for AltGr modifiers on Windows, contributed by stk stk@ableton.com

Additionally:

• Support for the termite (defunct) was removed from the built-in terminals. The fallback support by parsing terminfo still works. The termite project is now abandoned and the project advises users to use Alacritty (which is natively supported in tcell.)
• Support for focus event reporting was added for Windows
• The Views API no longer uses deprecated tcell functions internally (#682)

Version 2.7.0 Feature Release

Significant changes in this release:

• Introduced ColorNone which can be used in a style to avoid changing the existing foreground or background color.
• Refactored the screen logic to provide better code reuse and facilitate extending the Screen API in future releases. (This changes internal APIs only)
• Color grew some methods to report a String() (color name) or CSS() (color hex string in CSS style)
• LockRegion() and Tty API changes from Tim Culverhouse tim@timculverhouse.com in support of Sixel coexistence. This does not itself provide support for Sixel graphics, but it allows tcell applications to be used with other sixel graphics libraries.
• Mouse focus reporting (see EnableFocus(), DisableFocus(), and EventFocus) courtesy of stk stk@ableton.com (I also added support for focus reporting in the WASM terminal.) Windows console does not report this yet.

The refactoring in particular will enable some further improvements. Also, we added more test cases and coverage. While much of tcell remains uncovered by formal testing, every improvement here is welcome.

I expect to follow up with another release soon -- things I'm hoping for are gpm mouse support for the linux console (oft-requested), refactoring wide character support to fix some long standing bugs, and convenience methods to apply content or style changes to a rectangular region of the screen. In the meantime, I hope you enjoy this release!

Fixes (relative to 2.6.0)
