On some canvases, when using Focus View, it is impossible to pan around the entire canvas because the range of allowed movement is offset. It appears that VRC considers the canvas's pivot point to be the center of the allowed movement range, so this occurs if the pivot happens to be in a location like the top left. It needs to be in the center for Focus View to work properly.

This is easy enough to fix for new worlds, but causes problems in existing worlds. Perhaps there is a better way to do this - can it use the centroid of the allowed movement range as the center point, ignoring the canvas's pivot point?
