/**
* 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.
