ADB: Mouse acceleration / Extended Report / Wheel Emulation

[tmk]

Acceleration

Current impl. of mouse accleration doesn't appear to be proper in ADB coverter. We can depend on OS setting.

I confirmed that Xorg/libinput can manage it well with Apple one-button mouse and Kensington Turbo Mouse 5.

This describes how libinput handles mouse acceleration.

This can seem to spoil mouse precision and resolution, converter Acceleration feature will be disabled or removed.

Extended Report

Most of ADB pointing devices won't require 16-bit report(-32767 to 32767).
Even Turbo Mouse 5 limts XY axes from -126 to 126 and 8-bit report is enough there.

16-bit Extend Report has no apparent drawback so far, leave this feature enabled.

Wheel Emulation

current configuration uses button 4 for wheel emulation by default.

This works well with Turbo Mouse 5 using button 4.
Xorg/libinput can also emulate scroll wheel, see man 4 libinput.

some user may want to use the button for other usage. Disable wheel emulation in default configuration?

[tmk]

These are disabled by default now.

A few works are still needed.

• Acceleration should be removed from adb_usb?
• Weel Emulation should be moved in tmk_core?
