Reads an ICO file and writes a CUR file. The ICO file should contain a single
image. If no outfile name is provided, the infile name is used to create an
outfile name by changing the extension ".ico" to ".cur".
Example:
%prog mycursor.ico -x 15 -y 16
This creates a file mycursor.cur with a hotspot at (15, 16).
