[PATCH 0/2] MR7102: winex11: Map mouse/touch event coordinates even without a hwnd.

[Rémi Bernon (＠rbernon)]

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=57601

First change is needed to ignore hidraw touchscreen devices, it happens for instance on the Steam Deck in desktop mode. Although we indeed support them with mouhid.sys, there are multiple issues with it:

* The input coordinates are raw and inconsistent with the system X display configuration (the Steam Deck default configuration has a 90° rotated screen).

* They come in first and cause duplicate touch events with the X11 touch events, which makes the X touch events to always be considered as secondary touch points.

[PATCH 2/2] winex11: Map mouse/touch event coordinates even without a hwnd.

From: Rémi Bernon

Some touch events don't have the window set properly, we don't really
need it but we need the mouse coordinate to be mapped correctly.
