Fixes small and displaced intro videos in Resident Evil (1996). The game has 320x240 videos. By default the game is started in native resolution and ddraw.dll shipped alongside the game fixes some compatibility issues (without that it fails to start on Windows the same way as on Wine), along with scaling to native resolution. After doing MCI_OPEN the game gets MCI window and resizes it to 639x479 centered withing the parent main window. That currently has no effect on Wine's rendering size and is fixed by patch 2. Then, while video becomes bigger and centered it is still too small, on Windows it is fullscreen. The shipped ddraw.dll not only scales through ddraw API but also hotpatches StretchBlt and scales that also in some way. But mciavi32 uses StretchDIBits currently which is not hotpatched. So most likely Windows is not using StretchDIBits there in MCI. That is already implemented in compatible way in msvfw32 and msvfw32 is used from mciavi32, so just using msvfw32 presentation function looks most straightforward. I omitted the tests with overlapped windows because the resulting size of the window is hardly predictable both on Windows and Wine. While MCI destination rectangle changes for those as well. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10560#note_135011
