### Changes from RasMol 2.7.2.1.1 (the final reference release of RasMol 2.7.2) to RasMol 2.7.3.1 include:

- Adjustment to the mouse handling for a better, more natural feel. Our thanks to C. Chigbo for the suggestion.
- Correction to cif.c for blanks after an initial quote mark.
- Correction to mswin31.c to restore lost initializations of ZRange and DialValue[8..9].
- Modifications by Mamoru Yamanishi to Imakefile and rasmol.c to use xforms for GUI file open. This patch needs the opens source xforms 1.0.90 library by Steve Lamont.
- Correction to molecule.c to correct input of xyz files. Thanks to Stuart Prescott.
- Revision to CPK colors by C. Chigbo. The new colors are called CPKNEW. The current CPK colors remain available as CPK.
- Correction to negative torsion angle monitors and to imprecise distance and angle monitors by C. Chigbo. This patch corrects the display of negative torsion angles caused by use of the unsigned short type, and correctys imprecise distance and angle displays. This extends the original patch which was just for torsion angles (torsion.patch). A side effect of this change is to limit the available range for distance monitors to approximately 327 Ångstroms.
- Initial code for display of solid Lee-Richards molecular surfaces. This patch adds the basic code for display of Lee-Richards surfaces with a new `Molecular Surface` menu item, and `surface molecule <probe radius>` and `surface solvent <probe radius>` commands.
- Corrections of ribbons 0, etc. commands by R. Chachra. With this patch, the `wireframe 0`, `ribbon 0`, `cartoon 0`, `backbone 0`, `strands 0` and `trace 0` commands work the same as these command with `off` instead of `0`.

    [16/01/00]    PV cmndline.c
                    In PerformMouseFunc() corrected MM_CLIP to access clipping with
                    the mouse, added MM_DEPT to access backclipping (depth) with the mouse.

    [16/01/00]    PV	transfor.h, transfor.c, token.h, token.c, script.c
                    Added ShadePower in DefineColourMap(), which brings some interesting
                    shade variations. Added ShadePowerTok and command "set shade x"
                    with x between -20 to 20.

    [29/09/99]    PV	molecule.c
                    Fixed bug in FindCisBonds() (no zeroing of last group cisbondflag);
                    Added ability to convert triple bond to single (CreateBondOrder())

    [24/09/99]    PV	cmndline.c
                    Correlated mouse binding to global variable MouseMode.

                    Added four new picking modes: select an atom: PickAtom; select
                    a group: PickGroup; select a chain: PickChain; modify bonding/add
                    multiple bonds: PickBond.   Allowed picking parameter shift = -1
                    when Ctrl key is down to deselect an atom (a group, a chain)
                    from the current selection. [Note by HJB 02/04/01 -- The UCB
                    and 2.7.2 bond picking was used in 2.7.2.1 instead of the
                    RasTop version]

                    (Adapted from RasTop 1.3) Added shortcuts for direct evaluations
                    of atomsets (BuildAtomSet(), SelectZoneExpr()).

    [14/07/99]    PV	abstree.c, transfor.c
                    Added shortcuts for direct evaluations of atomsets (BuildAtomSet(),
                    SelectZoneExpr()); gain up to 15 seconds of computer time on very
                    large molecules.

                    Remove all use of the toolbar, converting to menu.
                    Change to ANSI C prototypes.  Revise bond and world
                    rotation logic to use full rotation, nor increment,
                    for improved accuracy.  Change Bond rotation logic to
                    preserve nesting of bonds without changing the original
                    coordinates.  Add database of selected bonds and logic

                    Add .ML2 and .SY2 extensions for Sybyl and MOL2.

### Changes adapted from UCB rasmol in creating RasMol 2.7.2:

Note: These mods do not reflect the complete source of UCB RasMol. In particular toolbar.h and toolbar.c have not been used in this pass, and the full source of UCB RasMol has not yet been recovered.

    [30/11/95]    GSG rasmac.c
                    Hide command window.  Add help screen menu logic.  Add hooks to
                    load multiple molecules.  Add toolbar menu to Windows menu.  Make
                    mouse moves control bond rotation, molecule rotation or world
                    rotation depending on tool bar button choices.  Same for scroll
                    bars.

    [29/11/95]    GSG	applemac.c
                    Change default background for printing to white.
                    Hook scroll bar H values to bond angle (BRotValue),
                    molecule rotation angle (DialValue[1]) or
                    world rotation angle (WRotValue[1]) depending on
                    toolbar settings.  Hook scroll bar V values to
                    molecule rotation angle (DialValue[0]) or
                    world rotation angle (WRotValue[0]) depending on
                    tool bar settings.  Allow file open when less than
                    MAX_MOLECULES molecules.

    [21/08/00]    GSG	font.h
                    Add characters for Angstrom and degree as replacements
                    for vertical bar and tilde.

    [16/11/95]    GSG render.c, render.h
                    Add PickBond.  Add hooks to draw multiple molecules.  Automatically
                    switch to the molecule of any picked atom.  Add monitor for picked
                    distance, angle or torsion angle.

    [14/11/95]    GSG transfor.c
                    Add hooks for bond rotation and global rotation.

    [14/11/95]    GSG vector.c, vector.h, wbrotate.c, wbrotate.h
                    New routines introduced with UCB mods to allow for
                    bond rotations and global rotation.

    [14/11/95]    GSG infile.c
                    Add fxorg, fyorg, fxorg for MDL molecule input only.

    [14/11/95]    GSG molecule.c, molecule.h
                    Add fxorg, fyorg, fxorg and list of bonds to atom database
                    for world and bond rotation.

    [11/11/95]    GSG multiple.c, multiple.h
                    New routine introduced with UCB mods to allow for
                    multiple molecules.

                    Add initialisation for multiple molecules.

### Changes from RasMol 2.7.1 to create RasMol 2.7.1.1:

    [21/01/01]    FGR, HJB	langsel.c, langsel_mac.c, mswin.c,  applemac.c
                    Installed translations for Edit menu on mac and PC
                    provided by Fernando Gabriel Ranea.

    [17/01/01]    FGR, HJB	langsel.c, langsel_mac.c
                    Corrections to translations by Fernando Gabriel Ranea, installed
                    by HJB with revisions to menu bar accelerators.

    [12/01/01]    HJB	applemac.c
                    Added include of langsel.h.  Added routine ReWriteStr255 to rewrite
                    menu bar items in place and tostr255 to convert other menu items
                    strings to Pascal form for use in SetmenuItemText.  Set up
                    ReDrawWindow to refresh all menu strings and then redraw the menu
                    bar.  Note that the rewrite of the main menu bar is _very_ risky
                    and may not survive system changes.

    [12/01/01]    HJB	command.c
                    Added include of langsel.h.  Remove redundant ErrorMsg array and Err...
                    definitions.  Change messages to reference MsgStrs.  Add English and
                    Spanish as commands calling SwitchLang.

    [12/01/01]    HJB	infile.c
                    Fix coordinate typo in load of XYZ and Mol2 molecules.

    [12/01/01]    HJB	langsel.c, langsel_mac.c, langsel.h
                    New routines to carry multi-lingual translations.  Many thanks to
                    Fernando Gabriel Ranea for the bulk of the Spanish translations,
                    and for creating the initial Spanish version of RasMol 2.7.1.  Note
                    that langsel.c uses the ANSI character set, while lansel_mac.c uses the
                    Macintosh character set.

    [12/01/01]    HJB	molecule.c
                    Added include of langsel.h.  Changed messages to reference MsgStrs.
                    Refixed D2O misparse, which had been previously fixed.  Mod had been
                    lost.

    [12/01/01]    HJB	mswin31.c
                    Added include of raswin.idm and langsel.h.  Included partial update
                    to printer logic.  Added ReDrawWindow as rewrite of menus with
                    ModifyMenu and RemoveMenu/AppendMenu calls.

    [12/01/01]    HJB	rasmac.c
                    Added include of langsel.h.  Added SwitchLang(English) calls
                    for initialization to main routine.

    [12/01/01]    HJB	rasmol.c
                    Add fix for broken math routines by referencing atan2.

    [12/01/01]    HJB	rasmol.h
                    Added include of langsel.h.  Added SwitchLang(English) calls
                    for initialization to main routine.

    [12/01/01]    HJB	raswin.c
                    Added include of langsel.h.  Changed font of command window to ANSI
                    character set.  Changed most messages to reference MsgStrs.  Add
                    SwitchLang(English) calls for initialization to WinMain.

    [12/01/01]    HJB	x11win.c
                    Restructured MenuItem and BarItem to make .text, .pos and .len
                    indirect, so that they can be fetched from MsgStrs, MsgAuxl and
                    MsgLens.  The .pos field is used to specify the character offset
                    of the acceleration key.  The main menu bar may now have non-zero
                    offsets.  All the menu items have been changed to MsgStrs[StrM...]
                    referecences, and added include of langsel.h.  Added ReDrawWindow
                    simply as a call to ReSizeWindow.  This is overkill, but appropriate
                    for these infrequent calls.

    [12/01/01]    HJB	tokens.h
                    Added tokens EnglishTok and SpanishTok.

    [12/01/01]    HJB	graphics.h
                    Added prototype of ReDrawWindow, a system-dependent call to be used
                    after updating menus on language changes.

    [12/01/01]    HJB	cmndline.c
                    Added include of langsel.h, changed prompts as follows:

                    "PDB file name:"		MsgStrs[StrPrmtPDB]
                    "Image file name:"		MsgStrs[StrPrmtImg]
                    "Molecule file name:"	MsgStrs[StrPrmtMol]

    [12/01/01]    HJB	tokens.c
                    Added the following tokens:

    [26/12/99]    HJB	mswin31.c
                    Do not reset Voxel Data for each chain.

    [02/10/99]    HJB	molecule.c
                    Update printer logic.
