Two-finger swipe gesture on macOS should have visual indicator

[tcr]

Describe the issue you encountered: The two-finger swipe gesture on macOS has no visual indication as you perform the swipe of whether it is activated (or will succeed). This may be intended but feels nonintuitive.

Expected behavior: Chrome has a visual arrow on the sides that appears as you swipe. Safari has a "page sliding" animation to indicate a swipe. Because Brave's swipe is calculated by velocity, a different type of indicator may be needed.

• Platform (Win7, 8, 10? macOS? Linux distro?): macOS
• Brave Version: 0.11.0dev
• Steps to reproduce:
  1. Open any page with a back history.
  2. Perform a two-finger swipe backward.
  3. See no visual changes.

Along these lines, is there a way to disable swipe navigation altogether? I have disabled it in my system settings but Brave seems to be the only one that doesn't respect that setting.

@ksmithut We have an issue for that: #5907.

@darkdh @NejcZdovc I'm seeing the back/forward arrows get larger when swiping up/down on a page, this this expected? cc @kjozwiak

Because you can't have 0 x-axis changes when you do vertical scroll. You will always have slightly horizontal movement which will be reflected onto the animation.
