The widget is based on a quadtree
along
which data is built. When the camera is far from the ground, the
scene is viewed at a low quad level and the displayed area is wide.
Inversely, when the camera is close to the ground, the scene is
viewed at a high level in the quad and the displayed area is tight
with a high resolution. This parameter lets you temporarily
overload the performance profile to be able to take a snapshot with
many loaded elements.
