Peter Hutterer fa091d7ac4 Differentiate between physical and virtual devices ... With passive libei contexts receiving events sent by the EIS implementation, the type of device changes significantly. While a relative input device could still send data in logical pixels, absolute devices may not have that luxury. Best example here is an external tablet (think: Wacom Intuos): that tablet has no built-in mapping to a screen and thus cannot capture input events in logical pixels. Address this by adding a device type, either virtual or physical. In terms of functionality, the device's type decides: - only virtual devices have regions - only physical devices have a size The event API remains as-is but the event data not represents either logical pixels (virtual devices) or mm (physical device). An EIS implementation connected to a passive libei context would likely create: - a virtual relative device (sending deltas in logical pixels) - one or more physical absolute devices (sending deltas in mm)		2022-04-04 05:28:36 +00:00
