Add a flight of the free camera to the test script.

Browse Source 
camfly moves the free camera by a distance and a turn in equal steps over a number of ticks, where camgo jumps: a
run can fly the view across an area without a route Link gets stuck on. A flight of 1.3 km round Hyrule Field showed
what it is not good for: the video memory in use stayed flat, the game loads and lets go of textures by where Link
is, not by where the camera looks.
