Now that all inputs are corrected to zero-centered, we can use getFlat()
to ignore movements that are just noise.
This eliminates a lot of drift when the controller is at rest, notably
on the character select screen in Melee.
Android reports the same physical axis multiple times for analog
triggers, and this handles this case.
There are also some controllers with broken mappings (eg the analog
triggers on a PS4 DualShock 4). These axis don't center correctly.
There are also some controllers (again, the PS4) that send both a button
press and an axis movement. This ignores the buttons so we can use the
analog axis. Otherwise, since the button comes before the axis moves
far we would always take the button.
Emulation needs to be running when the surface is destroyed, but we want
to pause in onStop. So call the surfaceDestroyed callback, as this
accomplished both.
The source Views don't need the transition name. We could get the name
from the sharedView via getTransitionName, but since the TV
ImageCardView isn't inflated in XML it would be to be manually set.
I'm not sure if that would be any cleaner than this.
called.
The user will get a brief system popup tutorial the first time it's
used, so we don't need to show them the menu every time. Once they
enable it by pulling down, hide again after 3s.
