[PATCH 0/5] MR551: win32u: Complete support for display modes in nulldrv.
With this series it's now possible to run and pass `user32:monitor` and `user32:sysparams` tests with nulldrv, and so most `user32` tests (except for a few desktop cursor position tests). This still requires some prefix configuration to enable the nulldrv driver, or a change like https://gitlab.winehq.org/rbernon/wine/-/commit/753368ad0ec52f03f8d6e78ca794... to enable it when `DISPLAY` environment variable is unset. This then shows that some of the user32 tests are failing with winex11 but passing with nulldrv, as in https://gitlab.winehq.org/rbernon/wine/-/commit/6d5f4109a514a0dc266899fcacfa.... -- https://gitlab.winehq.org/wine/wine/-/merge_requests/551
