This is a major overhaul of the hardware abstraction layer. A few notes: General platform distinction happens in frontend/device.lua which will delegate everything else to frontend/device/<platform_name>/device.lua which should extend frontend/device/generic/device.lua Screen handling is implemented in frontend/device/screen.lua which includes the *functionality* to support device specifics. Actually setting up the device specific functionality, however, is done in the device specific setup code in the relevant device.lua file. The same goes for input handling.
