A simple font class.
This is very impoverished by today's standards... Our font definitions only support fixed width and consist of the 95 characters (the first one is a space):
as created by AppMedia/app-font2c.C from an image of these characters. See writeText() in Image/DrawOps.H for a function that uses fonts.

| SimpleFont::~SimpleFont | ( | ) |
Destructor.
Definition at line 96 of file SimpleFont.C.
| const unsigned char * SimpleFont::charptr | ( | const int | c | ) | const |
Helper function to get a pointer to a specific char.
a Pointer to 'space' is returned if c < 32 or c > 126

| SimpleFont SimpleFont::FIXED | ( | const uint | width | ) | [static] |
Pseudo-constructor to get a font with fixed width.
Supported widths include: 6, 7, 8, 9, 10, 14 and 20.
