load_txt_font - Loads a font script. Allegro game programming library.
FONT *load_txt_font(const char *filename, RGB *pal, void
This function can be used to load scripted fonts. The script file contains a
number of lines in the format "filename start end", which specify
the source file for that range of characters, the Unicode value of the first
character in the range, and the end character in the range (optional, if left
out, the entire input file will be grabbed). If the filename is replaced by a
hyphen, more characters will be grabbed from the previous input file. For
example, the script:
ascii.fnt 0x20 0x7F
- 0xA0 0xFF
would import the first 96 characters from ascii.fnt as the range 0x20-0x7F, the
next 96 characters from ascii.fnt as the range 0xA0-0xFF, and the entire
contents of dingbats.fnt starting at Unicode position 0x1000.
Returns a pointer to the font or NULL on error. Remember that you are
responsible for destroying the font when you are finished with it to avoid
