Convert 26x26 Image to Tool Icon

26px_Image_to_Tool_Icon.ijm

// This macro converts a 26x26 8-bit image to a tool macro icon
// string. Ideally, the image should have no more than 16 colors.
// Includes seven examples that, with the exception of the 
// "Lena Tool", were created by converting website favicons
// (http://en.wikipedia.org/wiki/Favicon).
// v1.0 : 4 April 2006
// v1.1 : 17 January 2021 : works with 26x26px images.
