Adjust mouse and gesture handling

[peak3d]

Description

Commit 1:
This PR affects mouse and touch behaviour:

• Don't change selected item in ListView during MouseMove and GesturePan
• Select element on GestureEnd (could be after inertial scroll), cancel inertial scroll when start / end of list is reached
• Fix selection on beginning / end if using Middle mouse wheel

Commit 2:

• Adjust gesture Longpress time from 1sec > 0.5 sec
• Reduce inertial scroll time (scroll after swipe) for low velocities
• Take DPI into account when calculating inertial scroll values

Motivation and Context

In the last period I tested lot on android phones / and for validation on my windows laptop with touch and mouse support. Navigating with mouse felt something nervous / stressing, this PR reduces select actions to have a more relexed navigation. Beside this it will save battery live due to much less image / content change actions.

How Has This Been Tested?

Navigate inside main menu and video library with android phone / windows laptop (touch and mouse)

Types of change

• Bug fix (non-breaking change which fixes an issue)
• Clean up (non-breaking change which removes non-working, unmaintained functionality)
• Improvement (non-breaking change which improves existing functionality)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that will cause existing functionality to change)
• Cosmetic change (non-breaking change that doesn't touch code)
• None of the above (please explain below)

Don't change selected item in ListView during MouseMove and GesturePan

This is a welcome change, it had always annoyed me slightly.

Could you split somewhere along the bullets in the description?

[garbear]

Thanks for splitting. You can see how it divided up the code into disparate components: gui/, input/ and platform/. Untangling the code was helpful for me.

Left some comments. I haven't worked with touch or mouse in the GUI yet, so I'm not able to analyze the logic, but if something breaks later that's what follow up PRs are for.

[peak3d]

I removed the android one - will be in a separate PR

[garbear]

I don't see any unresolved comments.

Jenkins build this please

I am developing my own skin which I plan to release for Kodi 19.
It is going to be a mouse... version of Embuary, but it won't be an Embuary mod, I code it from scratch based on Estuary's code.
I am using Kodi with mouse only, even on my HTPC.

This change is very welcome for Estuary for example (Estuary is using fixedlists in all list views), it works brilliantly for fixedlist containers but feels not natural for panels, at least it doesn't for me.
Is there any hope for this to be enabled/disabled in the skin code of a container?
I would love to use it for fixedlists but not for panels or normal lists.

Some screenshots of my mouse skin, I even managed to make home widgets to scroll with a mouse by using hidden containers, (the main reason I am developing this skin, mouse handling of widgets).

[olympus123]

Some screenshots of Estuary.
In both cases I am focusing with my mouse Kodi's Media Settings.
The second screenshot seems confusing to me.

[peak3d]

I'll revert the mouse part, except the fix for middle wheel later the day

[olympus123]

Thank you peak3d, if you find time please have a look if you can keep this behaviour for fixedlists only.
You have been right that fixedlists work so much better with your enhancements.
Keep up your amazing work.

Any luck in reverting the mouse part @peak3d? On OSX mouse can't be used to navigate left nav or tiled menus.

BTW, cursors work OK, so there is a workaround.
