Inputs to MOVE, SCALE, ROTATE, ARRAY, OFFSET and the rest are checked for
being finite, but finite inputs can still overflow: moving by 1e308 twice
put a circle at infinity, after which inspect showed null coordinates,
the extents were null and a DXF save wrote it at 0,0.
After a command changes the drawing (JSON `execute`, grip edits, and an
interactive command when it ends), the objects it changed are checked:
every number in their fields and their extents must be finite. If not,
the drawing and selection are put back, no undo step is recorded and the
command fails with "the result is too large: object … would get infinite
or undefined coordinates. Nothing was changed".
