perf(clipboard): derive the paste anchor from bounding boxes

Browse source 
COPYCLIP/CUTCLIP computed the clipboard anchor by tessellating every
selected entity and averaging all wire vertices — O(total geometry),
~250 ms when copying a whole drawing. The anchor only fixes which point
of the selection sits under the cursor at paste, so the mean of each
entity's bounding-box centre is an equally valid, far cheaper origin.
