[really minor] mouse wheel tilt (buttons 6 and 7 per xev) not passed to windows HVM correctly

[tonsimple]

Qubes OS version (e.g., R3.2):

3.2

Affected TemplateVMs (e.g., fedora-23, if applicable):

WIndows 7 HVM

---

Expected behavior:

If tilt works with normal fedora and debian appvms (tested, it works, tilting Logitech Performance MX wheel works in a qubes linux-based appvm with firefox if xorg.conf is correctly configured to use udev driver and correct event) then tilt should also work in Windows HVM

Actual behavior:

Windows ignores wheel tilt or interprets it as a random button click

Meanwhile, linux appvms are reacting to tilt correctly

Steps to reproduce the behavior:

Have a mouse with wheel tilt.
Have it configured so tilt events are detected and correctly passed to linux AppVMs
Have a windows 7 HVM with Qubes Tools installed
Start windows HVM
Try using the tilt feature

General notes:

I understand it's like, really really small issue :)
But I really like tilt :( and maybe someone knows a clever workaround or a fix will be easy.

Slightly offtopic: without Qubes tools it will not work, as gui-agent in qemu does not have it implemented:
https://github.com/QubesOS/qubes-gui-agent-xen-hvm-stubdom/blob/master/gui-agent-qemu/qubes-gui.c#L337-L346

On topic: Windows gui-agent (aka wga) does not have it implemented either:
https://github.com/QubesOS/qubes-gui-agent-windows/blob/master/gui-agent/vchan-handlers.c#L236-L265

Looking at documentation, adding Button6 and Button7 as MOUSEEVENTF_HWHEEL should do the trick.
Anyone care to send pull request?

Just to make sure - check wga logs to see if "unknown button pressed/released " messages are logged and button numbers are 6 and 7.

Yes, exactly. And buttons indeed are 6 and 7.
