* The following tags are recognized at NewObject() time by
* pointerclass:
*
* POINTERA_BitMap (struct BitMap *) - Pointer to bitmap to
* get pointer imagery from. Bitplane data need not be
* in chip RAM.
* POINTERA_XOffset (LONG) - X-offset of the pointer hotspot.
* POINTERA_YOffset (LONG) - Y-offset of the pointer hotspot.
* POINTERA_WordWidth (ULONG) - designed width of the pointer in words
* POINTERA_XResolution (ULONG) - one of the POINTERXRESN_ flags below
* POINTERA_YResolution (ULONG) - one of the POINTERYRESN_ flags below
*

POINTERA_XResolution EQU (POINTERA_Dummy+$05)
POINTERA_YResolution EQU (POINTERA_Dummy+$06)
* These are the choices for the POINTERA_XResolution attribute which
* will determine what resolution pixels are used for this pointer.
*
* POINTERXRESN_DEFAULT (ECS-compatible pointer width)
* = 70 ns if SUPERHIRES-type mode, 140 ns if not
*
* POINTERXRESN_SCREENRES
* = Same as pixel speed of screen
*
* POINTERXRESN_LORES (pointer always in lores-like pixels)
* = 140 ns in 15kHz modes, 70 ns in 31kHz modes
*
* POINTERXRESN_HIRES (pointer always in hires-like pixels)
* = 70 ns in 15kHz modes, 35 ns in 31kHz modes
*

* These are the choices for the POINTERA_YResolution attribute which
* will determine what vertical resolution is used for this pointer.
*
* POINTERYRESN_DEFAULT
* = In 15 kHz modes, the pointer resolution will be the same
* as a non-interlaced screen. In 31 kHz modes, the pointer
* will be doubled vertically. This means there will be about
* 200-256 pointer lines per screen.
*
* POINTERYRESN_HIGH
* POINTERYRESN_HIGHASPECT
* = Where the hardware/software supports it, the pointer resolution
* will be high. This means there will be about 400-480 pointer
* lines per screen. POINTERYRESN_HIGHASPECT also means that
* when the pointer comes out double-height due to hardware/software
* restrictions, its width would be doubled as well, if possible
* (to preserve aspect).
*
* POINTERYRESN_SCREENRES
* POINTERYRESN_SCREENRESASPECT
* = Will attempt to match the vertical resolution of the pointer
* to the screen's vertical resolution. POINTERYRESN_HIGHASPECT also
* means that when the pointer comes out double-height due to
* hardware/software restrictions, its width would be doubled as well,
* if possible (to preserve aspect).
