cannot select pseudobonds to cartoon

[Elaine Meng]

Usually cannot get a pseudobond between cartoon segments to be selected with Ctrl-click.

...then try Ctrl-click on ribbon-ribbon pseudobonds. Occasionally I can select one, but then never an additional one thereafter. I just get "select clear" over and over in the Log.

The selection code must be operating as though the pseudobonds were being drawn between the atomic coordinates rather than the adjusted ribbon coordinates. If I switch the depiction to sticks, I can select the pseudobonds without problem.

Possibly the same as #2466

Fixed in 1.2.

Pseudobond picking was not using ribbon coordinates when pseudobond went to ribbon.

As noted in #2466 the pb_coords and pb_scene_coords Atoms methods are looping over all the pseudobonds which will give very poor performance. I converted those to use C++ code.
