Persistent Frame in Profile Window about lag HOT 4 CLOSED

Current hypothesis: Check Profile::loadprofile, even though it's got a mutex locking the whole method, it could be called with some arguments, block, those arguments become out of date, and then the method unblocks and loads the wrong set of points. Unsure though how this could cause this particular bug.

Observed to not be restricted to getting a new profile. Has now occurred when just changing the profile location and moving in the 2d overview window without refreshing the profile.

Turns out to occur when: the profile is drawn on the overview, and a point is queried with right-click.

from lag.

Mish-mashed BoxOverlay into doing the job of overlaying the point selection box rather than the LagDisplay::overlayBox method (which probably causes this). That means:

1. All the overlays are being consistently drawn in the same way
2. The point selection box is now something that persists on the dataset and maps to it spatially, meaning its size will subsequently change when you zoom in+out. It might be wise to tweak BoxOverlay to optionally not do this.
