 Using the hardware cursor(s) when possible saves CPU and gets rid of
 flicker, and when running videos, becomes nearly essential for nice
 behavior.

 The LX has a 48x64 ARGB hardware cursor support, and a 2 plane 64x64
 cursor that can be used during use of the video unit. (note that due to
 rotation, this means the largest cursor that can reliably always use the
 hardware is therefore 48x48, or in portrait mode you'll use the software
 cursor if the vertical is more than 48 pixels).

 The X server will dither down an ARGB cursor to two planes for you,
 according to keithp.
