* I changed this a little bit to correctly handle fonts with missing char provided.
* A font is not required to provide all the 256 chars and can even have hole.
* When a character not defined is displayed, PalmOS uses the "missingChar".
* The missing char is an additional set after the end of the font.
* You can specify it (you should actually) in a Font file using GLYPH -1.
* This should be the last one in the file.
* Thus you can control what is displayed if something using your font tries to
* display an unsupported character.
*
* I changed PilRC to correctly handle font definition files containing or not the missing char.
*
* Additionally, the columns array must contain n+1 items including the col past the last char
* used to compute the size of the last char by some tools. I also fixed that.
