 my $cursor = SDL::Cursor->new(
     \@data, \@mask, $width, $height, $hotspot_left, $hotspot_top
 );

Create a cursor using the specified data and mask (in MSB format). The cursor is created in black and white according to the following:

 Data / Mask   Resulting pixel on screen
    0 / 1      White
    1 / 1      Black
    0 / 0      Transparent
    1 / 0      Inverted color if possible, black if not.

If you want to have color cursor, then this function is not for you. Instead, you should hide the cursor with "SDL::Mouse::show_cursor(SDL_DISABLE)". Then in your main loop, when you draw graphics, draw a "SDL::Surface" at the location of the mouse cursor.

Example:

 use SDL;
 use SDL::Video;
 use SDL::Mouse;
 use SDL::Cursor;

 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,
     0b11100111,
     0b11000011,
     0b11000011,
     0b11100111,
     0b01111110,
     0b00111100
 );
 my $cursor = SDL::Cursor->new(\@data, \@mask, 8, 8, 0, 0);
 sleep(1);

 SDL::Mouse::set_cursor($cursor);
 sleep(5);

The width of cursors work in groups of 8. If the width is above 8, twice the amount of elements in @data and @mask are required. If the width is above 16, three times are required, and so on. For example, if you wanted a 9 pixel crosshair you might do the following:

 my @data = (
     0b00001000,0b00000000,
     0b00001000,0b00000000,
     0b00001000,0b00000000,
     0b00001000,0b00000000,
     0b11111111,0b10000000,
     0b00001000,0b00000000,
     0b00001000,0b00000000,
     0b00001000,0b00000000,
     0b00001000,0b00000000,
 );
 my @mask = @data;

 my $cursor = SDL::Cursor->new(\@data, \@mask, 9, 9, 4, 4);

The hotspot is offset by 4 pixels because a crosshair clicks from the center instead of the top left.
