Description

As it stands now on the WiiU it's not possible to use the WiiU Gamepad's Touchscreen to navigate the Ozone UI (actually any UI)
It has been said that the WiiU currently only supports 1 of the the 4 types of Touch Input that Retroarch uses..
There is: Lightgun, Mouse, Touch and Absolute Touch.
All Cores that support Lightgun/Zapper work with the WiiU Gamepad but those same Cores cant use the Gamepad as a Mouse device.
Would it be possible to add the other 3 Touch Inputs so The WiiU Gamepad can be used not only to navigate the Ozone UI but also enable the ability to use the WiiU Gamepad as a Mouse Input for Cores that can use it (Eg Mame/Amiga/AtariST/Snes Cores/others)

Research direction

Start by tracing RetroArch’s WiiU input handling and how Ozone receives navigation events; the issue does not name a file or test. Done means the WiiU Gamepad supports Lightgun, Mouse, Touch, and Absolute Touch input, can navigate Ozone, and can act as mouse input for compatible cores.
