285 * For pointers without alpha channel the XOR mask pixels are 32 bit values: (lsb)BGR0(msb).
286 * For pointers with alpha channel the XOR mask consists of (lsb)BGRA(msb) 32 bit values.
287 *
288 * Guest driver must create the AND mask for pointers with alpha channel, so if host does not
289 * support alpha, the pointer could be displayed as a normal color pointer. The AND mask can
290 * be constructed from alpha values. For example alpha value >= 0xf0 means bit 0 in the AND mask.
291 *
292 * The AND mask is 1 bpp bitmap with byte aligned scanlines. Size of AND mask,
293 * therefore, is cbAnd = (width + 7) / 8 * height. The padding bits at the
294 * end of any scanline are undefined.
295 *
296 * The XOR mask follows the AND mask on the next 4 bytes aligned offset:
297 * uint8_t *pXor = pAnd + (cbAnd + 3) & ~3
298 * Bytes in the gap between the AND and the XOR mask are undefined.
299 * XOR mask scanlines have no gap between them and size of XOR mask is:
300 * cXor = width * 4 * height.

1041 * The 8th bit is reserved for distinguishing between 32-bit and 64-bit
1042 * processes in future 64-bit guest additions.
1043 *
1044 * While windows IOCTL function number has to start at 2048 and stop at 4096 there
1045 * never was any need to do this for everyone. A simple ((Function) | 0x800) would
1046 * have sufficed. On Linux we're now intruding upon the type field. Fortunately
1047 * this hasn't caused any trouble because the FILE_DEVICE_UNKNOWN value was set
1048 * to 0x22 (if it were 0x2C it would not have worked soo smoothly). The situation
1049 * would've been the same for *BSD and Darwin since they seems to share common
1050 * _IOC() heritage.
1051 *
1052 * However, on good old OS/2 we only have 8-bit handy for the function number. The
1053 * result from using the old IOCTL function numbers her would've been overlapping
1054 * between the two ranges.
1055 *
1056 * To fix this problem and get rid of all the unnecessary windowsy crap that I
1057 * bet was copied from my SUPDRVIOC.h once upon a time (although the concept of
1058 * prefixing macros with the purpose of avoid clashes with system stuff and
1059 * to indicate exactly how owns them seems to have been lost somewhere along
1060 * the way), I've introduced a VBOXGUEST_IOCTL_CODE for defining generic IN/OUT
1061 * IOCtls on new ports of the additions.
1062 *
1063 * @remarks When creating new IOCtl interfaces keep in mind that not all OSes supports
1064 * reporting back the output size. (This got messed up a little bit in VBoxDrv.)
1065 *
1066 * The request size is also a little bit tricky as it's passed as part of the
1067 * request code on unix. The size field is 14 bits on Linux, 12 bits on *BSD,
1068 * 13 bits Darwin, and 8-bits on Solaris. All the BSDs and Darwin kernels
1069 * will make use of the size field, while Linux and Solaris will not. We're of
1070 * course using the size to validate and/or map/lock the request, so it has
1071 * to be valid.
1072 *
1073 * For Solaris we will have to do something special though, 255 isn't
1074 * sufficent for all we need. A 4KB restriction (BSD) is probably not
1075 * too problematic (yet) as a general one.
1076 *
1077 * More info can be found in SUPDRVIOC.h and related sources.
1078 *
1079 * @remarks If adding interfaces that only has input or only has output, some new macros
1080 * needs to be created so the most efficient IOCtl data buffering method can be
1081 * used.
