MEASUREGEOM gains a Quick option. As the cursor moves, the nearest
drawn geometry along the working plane's X and Y lines through it is
measured live: cyan measurement lines and a Horizontal/Vertical readout
by the cursor. A click prints the current readout and keeps measuring;
Enter ends the command. The rays go through the scene's interaction
index, so large drawings stay responsive.
A structure-pick command whose miss message is empty now gets the click
as a plain point instead of an error.
