[PATCH v5 1/3] winex11.drv: Add 'EDID' registry key to every monitor device.
Extended display identification data (EDID) is a set of data that is provided by a display to describe its capabilities to a graphics adapter. EDID data allows a computer to detect the type of monitor that is connected to it. EDID data includes the manufacturer name, the product type, the timings that are supported by the display, the display size, as well as other display characteristics. EDID is defined by a standard published by the Video Electronics Standards Association (VESA). In Windows, every display device has an associated 'EDID' registry key containing this data. Applications can read and parse it to get the display capabilities. In Linux, we can get each monitor's EDID using the RANDR X extension. This patch fixes, for example, monitor detection in the UE-based game 'Industries of Titan'.

Some applications use the EDID property of the monitor device to detect supported resolutions, and set the viewport size. Add a computed EDID to the virtual desktop monitor device to allow the virtual desktop driver to be better compatible with such applications. Most fields of the EDID contain details that are of no relevance to applications, so populate only the native resolution and physical monitor dimensions. This should cover the vast majority of use cases.
