[PATCH v6 0/4] MR5422: win32u: Simplify virtual desktop mode by reporting all sources as detached.
-- v6: win32u: Introduce a new add_virtual_modes helper. winex11: Let win32u decide when to force update the display cache. win32u: Don't force refresh the display cache on thread desktop change. winex11: Report all sources as detached in virtual desktop mode. https://gitlab.winehq.org/wine/wine/-/merge_requests/5422

Put this to where the old update_display_devices() was so the diff is clearer. I can move it around before or keep it where it is but there are changes to the function regardless and the diff won't be much clearer. Keeping it where it is would require to forward declare `add_virtual_source`, or to move that one instead.

ChangeDisplaySettings may fail already with the current code, for various reasons.
Ultimately, with full display device virtualization in mind, I think it will be interesting to keep both these physical / virtual sources. Instead of a winecfg switch, I can imagine display devices being virtualized dynamically from a physical output to a dedicated window, or de-virtualized from a window to a physical source. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5422#note_68426

With multiple monitors, virtual desktop mode won't work well on the non-primary display.
We should IMO implement support for non-primary virtual sources, which needs an initial, and a maximum display resolution. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5422#note_68429

Instead of a winecfg switch, I can imagine display devices being virtualized dynamically from a physical output to a dedicated window, or de-virtualized from a window to a physical source. Exposing these detached sources produces the following errors when using virtual desktop.

I think we can initialize the current modes in win32u as well instead of doing it in explorer.exe. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5422#note_68920
