A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

Verification: type checked

```yh
using dolphin.lightlab

// Same image.

float argument_x = 1.0
float argument_y = 1.0

bool result = instance.SameImage(argument_world, argument_x, argument_y, argument_z, argument_yaw, argument_pitch, argument_fov, argument_revision)
Console.Log(Text.From(result))

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
