// There are two fonts in the "Tiny 3x5" family.
//
// The first is a slightly modified version of the 3x5 font
// I created in 1980 for the Apple ][.  It is no longer
// monospaced as there are some 1 and 2 column symbols here
// as well.
//
// The numbers in this font are also in a blocky rather than
// rounded style.  I think that improves readability and also
// distinguishes numbers from letters more.
//
// This font uses only square pixels.
//
// The encoding for each character is:
//
//     [C, I1, I2, ..., In]
//
// where C is the number of columns of width used by the character
// and the indices are the row-major sequential indices into the character
// array (starting at zero for the uper left).
//
// Use the grid editor at https://mckoss.com/labs/models/grid-edit.html
// to modify individual letters.
