Byte = [16_00 .. 16_ff];
This part has to be modified for each new cursor pixmap. You can use
the bitmap program (a standard X utility) to design the cursor.
bitmap saves a file that contains a snippet of C code. Use this
code as a template to fill in width, height, and bits
(remember to replace 0x by 16_ when copying bits).
You also have to fill in hotspot and color.

width = 36;
height = 36;
