Interactive fly navigation modal operator (flying around in space).

Defines VIEW3D_OT_fly modal operator.

Note
Similar logic to view3d_navigate_walk.cc changes here may apply there too.

◆ eFlyPanState

enum eFlyPanState

Relative view axis locking - xlock, zlock.

Enumerator
FLY_AXISLOCK_STATE_OFF 

Disabled.

FLY_AXISLOCK_STATE_IDLE 

Enabled but not checking because mouse hasn't moved outside the margin since locking was checked an not needed when the mouse moves, locking is set to 2 so checks are done.

FLY_AXISLOCK_STATE_ACTIVE 

Mouse moved and checking needed, if no view altering is done its changed back to FLY_AXISLOCK_STATE_IDLE.
