1413	Visualisation/handling of altlocs	Tristan Croll	Tom Goddard	"Designating as ""Core"" and assigning to Eric, but is related to both core and graphics.

This is not urgent for me, but something that would be great to have available in time for ISOLDE 1.0b3. Would be great to have a visualisation mode that shows all altlocs present (would be particularly cool with atom/bond radii scaled according to occupancy), and an API call to set which altloc (where altlocs are present) currently responds to generic 'Atoms.coords' calls. 

The point of this is that when model-building it's very important to be able to see where you have altlocs (because otherwise all you see is unexplained density). In terms of simulation it would be undesirable to have them all active at once (it's technically possible - one can designate sets of atoms as not interacting with each other - but keeping them well-behaved would be a pain in the neck). With the above, it would be very simple to implement the ability to switch between altlocs in a running simulation, allowing them to be fitted one at a time."	enhancement	assigned	moderate		Graphics				Eric Pettersen				all	ChimeraX
