195 * For pointers with alpha channel the XOR mask consists of (lsb)BGRA(msb) 32 bit values.
196 *
197 * Guest driver must create the AND mask for pointers with alpha channel, so if host does not
198 * support alpha, the pointer could be displayed as a normal color pointer. The AND mask can
199 * be constructed from alpha values. For example alpha value >= 0xf0 means bit 0 in the AND mask.
200 *
201 * The AND mask is 1 bpp bitmap with byte aligned scanlines. Size of AND mask,
202 * therefore, is cbAnd = (width + 7) / 8 * height. The padding bits at the
203 * end of any scanline are undefined.
204 *
205 * The XOR mask follows the AND mask on the next 4 bytes aligned offset:
206 * uint8_t *pXor = pAnd + (cbAnd + 3) & ~3
207 * Bytes in the gap between the AND and the XOR mask are undefined.
208 * XOR mask scanlines have no gap between them and size of XOR mask is:
209 * cXor = width * 4 * height.
