[PATCH 0/1] MR7478: user32: Use the correct DPI in AdjustWindowRect(Ex) when DPI virtualization is active.

[Brendan Shanks (＠bshanks)]

`AdjustWindowRect(Ex)` were using the system DPI even in non-DPI-aware applications, leading to some bizarre behavior.

An easy test for this is to remove the DPI awareness from `winemine`'s manifest, set the system DPI to 192, then run `winemine` and click the smiley face. Every click on the smiley face will move the window up by ~30 pixels.

A copy of ioquake3 with DPI awareness removed would also constantly enlarge its window vertically.

[PATCH 1/1] user32: Use the correct DPI in AdjustWindowRect(Ex) when DPI virtualization is active.
