/**
 * Callback invoked by libVNCServer when it receives a new cursor image from
 * the VNC server. The cursor image itself will be split across
 * client->rcSource and client->rcMask, where rcSource is an image buffer of
 * the format natively used by the current VNC connection, and rcMask is an
 * array if bitmasks. Each bit within rcMask corresponds to a pixel within
 * rcSource, where a 0 denotes full transparency and a 1 denotes full opacity.
 *
 * @param client
 *     The VNC client associated with the VNC session in which the new cursor
 *     image was received.
 *
 * @param x
 *     The X coordinate of the new cursor image's hotspot, in pixels.
 *
 * @param y
 *     The Y coordinate of the new cursor image's hotspot, in pixels.
 *
 * @param w
 *     The width of the cursor image, in pixels.
 *
 * @param h
 *     The height of the cursor image, in pixels.
 *
 * @param bpp
 *     The number of bytes in each pixel, which must be either 4, 2, or 1.
