use custom made cursors. Note that the cursors can only be in black and
white.</p>

<p>Create a cursor using the specified data and mask (in MSB format). The cursor width must be a multiple of 8 bits.</p>
<p>The cursor is created in black and white according to the following:</p>
<pre> Data / Mask   Resulting pixel on screen
    0 / 1      White
    1 / 1      Black
    0 / 0      Transparent
    1 / 0      Inverted color if possible, black if not.

</pre>
<p>Cursors created with this function must be freed with SDL_FreeCursor.</p>
<p>If you want to have color cursor, then this function is not for you; instead, you must hide normal system cursor with <code>SDL::Cursor-</code>new&gt;
and in your main loop, when you draw graphics, also draw a <code>SDL::Surface</code> at the location of the mouse cursor. </p>
<p>Example:</p>
<pre> use SDL;
 use SDL::Cursor;
 use SDL::Mouse;
 use SDL::Video;

 SDL::init(SDL_INIT_VIDEO);
 SDL::Video::set_video_mode( 640, 480, 16, SDL_SWSURFACE);

 my @data = (
     0b00000000,
     0b00111100,
     0b01111110,
     0b01111110,
     0b01111110,
     0b01111110,
     0b00111100,
     0b00000000

 my @mask = (
     0b00111100,

     0b01111110,
     0b00111100
