    /* the PlanePick and PlaneOnOff variables work much the same way as the
     * equivalent GELS Bob variables.  It's a space-saving
     * mechanism for image data.  Rather than defining the image data
     * for every plane of the RastPort, you need define data only
     * for the planes that are not entirely zero or one.  As you
     * define your Imagery, you will often find that most of the planes
     * ARE just as color selectors.  For instance, if you're designing
     * a two-color Gadget to use colors one and three, and the Gadget
     * will reside in a five-plane display, bit plane zero of your
     * imagery would be all ones, bit plane one would have data that
     * describes the imagery, and bit planes two through four would be
     * all zeroes.  Using these flags avoids wasting all
     * that memory in this way:  first, you specify which planes you
     * want your data to appear in using the PlanePick variable.  For
     * each bit set in the variable, the next "plane" of your image
     * data is blitted to the display.	For each bit clear in this
     * variable, the corresponding bit in PlaneOnOff is examined.
     * If that bit is clear, a "plane" of zeroes will be used.
     * If the bit is set, ones will go out instead.  So, for our example:
     *	 Gadget.PlanePick = 0x02;
     *	 Gadget.PlaneOnOff = 0x01;
     * Note that this also allows for generic Gadgets, like the
     * System Gadgets, which will work in any number of bit planes.
     * Note also that if you want an Image that is only a filled
     * rectangle, you can get this by setting PlanePick to zero
     * (pick no planes of data) and set PlaneOnOff to describe the pen
     * color of the rectangle.
     * NOTE:  Intuition relies on PlanePick to know how many planes
     * of data are found in ImageData.	There should be no more
     * '1'-bits in PlanePick than there are planes in ImageData.

/* New for V39, Intuition supports the IESUBCLASS_NEWTABLET subclass
 * of the IECLASS_NEWPOINTERPOS event.	The ie_EventAddress of such
 * an event points to a TabletData structure (see below).
 * The TabletData structure contains certain elements including a taglist.
 * The taglist can be used for special tablet parameters.  A tablet driver
 * should include only those tag-items the tablet supports.  An application
 * can listen for any tag-items that interest it.  Note: an application
 * must set the WA_TabletMessages attribute to TRUE to receive this
 * extended information in its IntuiMessages.
 * The definitions given here MUST be followed.  Pay careful attention
 * to normalization and the interpretation of signs.
 * TABLETA_TabletZ:  the current value of the tablet in the Z direction.
 * This unsigned value should typically be in the natural units of the
 * tablet.  You should also provide TABLETA_RangeZ.
 * TABLETA_RangeZ:  the maximum value of the tablet in the Z direction.
 * Normally specified along with TABLETA_TabletZ, this allows the
 * application to scale the actual Z value across its range.
 * TABLETA_AngleX:  the angle of rotation or tilt about the X-axis.  This
 * number should be normalized to fill a signed long integer.  Positive
 * values imply a clockwise rotation about the X-axis when viewing
 * from +X towards the origin.
 * TABLETA_AngleY:  the angle of rotation or tilt about the Y-axis.  This
 * number should be normalized to fill a signed long integer.  Positive
 * values imply a clockwise rotation about the Y-axis when viewing
 * from +Y towards the origin.
 * TABLETA_AngleZ:  the angle of rotation or tilt about the Z axis.  This
 * number should be normalized to fill a signed long integer.  Positive
 * values imply a clockwise rotation about the Z-axis when viewing
 * from +Z towards the origin.
 *	Note: a stylus that supports tilt should use the TABLETA_AngleX
 *	and TABLETA_AngleY attributes.	Tilting the stylus so the tip
 *	points towards increasing or decreasing X is actually a rotation
 *	around the Y-axis.  Thus, if the stylus tip points towards
 *	positive X, then that tilt is represented as a negative
 *	TABLETA_AngleY.  Likewise, if the stylus tip points towards
 *	positive Y, that tilt is represented by positive TABLETA_AngleX.
 * TABLETA_Pressure:  the pressure reading of the stylus.  The pressure
 * should be normalized to fill a signed long integer.	Typical devices
 * won't generate negative pressure, but the possibility is not precluded.
 * The pressure threshold which is considered to cause a button-click is
 * expected to be set in a Preferences program supplied by the tablet
 * vendor.  The tablet driver would send IECODE_LBUTTON-type events as
 * the pressure crossed that threshold.
 * TABLETA_ButtonBits:	ti_Data is a long integer whose bits are to
 * be interpreted at the state of the first 32 buttons of the tablet.
 * TABLETA_InProximity:  ti_Data is a boolean.	For tablets that support
 * proximity, they should send the {TABLETA_InProximity,FALSE} tag item
 * when the stylus is out of proximity.  One possible use we can forsee
 * is a mouse-blanking commodity which keys off this to blank the
 * mouse.  When this tag is absent, the stylus is assumed to be
 * in proximity.
 * TABLETA_ResolutionX:  ti_Data is an unsigned long integer which
 * is the x-axis resolution in dots per inch.
 * TABLETA_ResolutionY:  ti_Data is an unsigned long integer which
 * is the y-axis resolution in dots per inch.
