tl;dr -> "center on self" feature with geolocation disabled in settings doesn't prompt for authorization or alert that authorization is off. instead, it places the user off the coast of Africa at (0,0).
steps to reproduce:
* use geoloqi app as usual
* disable geoloqi's location access in settings
* try to use geoloqi late, tap the crosshair, wind up in the ocean.
for a while, i thought the symptom was from being international with data roaming turned off, but the switch in settings was set to off for geoloqi. flipping it brought me back to reality.
