[PATCH] Treat Qemu and VirtualBox tablet-style inputs as absolute coordinate mouse pointer

[Jon Doe]

Hi,

I find it difficult to work with the current "invisible finger" or "drag pointer" interface provided to the virtual absolute coordinate pointing devices. Instead, this patch classifies them as a regular mouse pointer (INPUT_DEVICE_CLASS_CURSOR), which is more intuitive to work with.

The patch looks for absolute coordinate x-y axis (ABS_X, ABS_Y) devices with a relative coordinate vertical mouse scroll wheel (REL_WHEEL), as provided by both "QEMU USB Tablet" and "VirtualBox USB Tablet" devices. Regular touch screens do not satisfy this condition, so they are left alone to be classified as INPUT_DEVICE_CLASS_TOUCH.

As a convenience, idc files are also attached to enable orientation aware movement in any rotation.

Looks promising.

However, the patch can't be applied clean to oreo-x86 branch.
Please provide a git-format patch to the latest oreo-x86 branch.
Thanks a lot!

Besides QEMU and VirtualBox, I have also added the same tablet-style
inputs support to VMware and Hyper-V based on your patch.
This is included in the 8.1-r1 release.
Thank you again for providing such a great feature!
