* fix anaglyph stereo in batch (headless) mode
* fix possible memory corruption with boolean settings
* measurement wizard: distances between states (all_states=on)
* get_fastastr: nucleic acid, by chain
* menu: A (Action) > group
* sequence viewer menu: ss (Secondary Structure)
* MAE export of groups (s_m_subgroupid)
* macOS: -O3 -fno-strict-aliasing (bugs/205)
* stick_round_nub for COLLADA export
* UTF-8 in feedback
* display_scale_factor (ported from Incentive PyMOL)
* dx map import: support "type float" and skewed delta
* fast PDBx/mmCIF and core CIF loading in C++
* new connect_mode=4 does bonding with components.cif dictionary
(mmCIF only, components.cif needs to be present in current
directory)
* gray out residues in the sequence viewer that are missing from the
current state; Read missing residues from mmCIF files
(_pdbx_unobs_or_zero_occ_residues records) so that they show up in
the sequence viewer
* add spider map reading support
* load "map" as ccp4 instead of throwing "ambiguous" error
* xyz write support
* Improve right-button zoom: use origin instead of clipping slab
center as depth indicator, fixes zoom speed when far clipping plane
is very far away
* don't use dynamic_width for nonbonded rep
