From the Manx 3.6 disks:

2> list intuition
Directory "intuition" on Friday 14-Oct-88
preferences.h               3662 rwed Today     05:17:01
screens.h                   1454 rwed Today     05:17:02
intuition.h                 9452 rwed Today     05:17:04
intuitionbase.h             4211 rwed Today     05:17:05
4 files - 44 blocks used

From the Amiga includes 1.2:

2> list intuition
Directory "intuition" on Friday 14-Oct-88
intuition.h                54944 rwed 31-Mar-87 15:52:18
intuitionbase.h            12975 rwed 31-Mar-87 15:52:07
2 files - 142 blocks used

The two extra files contain part of the old intuition.h, and contain at the
very least a bigger preferences structure. No comments, though...

From Amiga includes 1.2, intuition.h:

    BYTE    RowSizeChange;     /* # to change gfxbase's NormalDisplayRows */
    BYTE    ColumnSizeChange;  /* # to change gfxbase's NormalDisplayColumns */
    BYTE    padding[14];    /* For further system expansion     */
};

From Aztec 3.6, preferences.h (my comments):

    BYTE sys_reserved1;	/* see below */
    BYTE sys_reserved2;
    UWORD PrintFlags;	/* presumably for the 1.3 drivers */
    UWORD PrintMaxWidth;
    UWORD PrintMaxHeight;
    UBYTE PrintDensity;
    UBYTE PrintXOffset;
    UWORD wb_Width;	/* Wonder what these are for, Hedley? */
    UWORD wb_Height;
    UBYTE wb_Depth;
    UBYTE ext_size;	/* This is a weird one */
};
#define RowSizeChange sys_reserved1
#define ColumnSizeChange sys_reserved2

I strongly suspect that there will at least be a published version of
1.3 includes that reflects this change, without the comments stripped
out and without the "sys_reserved[12]" stuff.

I discovered this when told my 'prefs' program (which assumed the Aztec 3.6
files) wouldn't compile with 3.4 and the Amiga 1.2 includes.

By the way, this means 'prefs' already works with the 1.3 prefs structure.
I suspect the 1.4 structure will be bigger.
