/* Special file formats handled here:
FON1 "console" fonts have the following header:
char Magic[4]; -- The characters "FON1"
uword CharWidth; -- Character cell width
uword CharHeight; -- Character cell height
The FON1 header is followed by RLE character data for all 256
8-bit ASCII characters.
FON2 "standard" fonts have the following header:
char Magic[4]; -- The characters "FON2"
uword FontHeight; -- Every character in a font has the same height
ubyte FirstChar; -- First character defined by this font.
ubyte LastChar; -- Last character definde by this font.
ubyte bConstantWidth;
ubyte ShadingType;
ubyte PaletteSize; -- size of palette in entries (not bytes!)
ubyte Flags;
There is presently only one flag for FON2:
FOF_WHOLEFONTKERNING 1 -- The Kerning field is present in the file
The FON2 header is followed by variable length data:
word Kerning;
-- only present if FOF_WHOLEFONTKERNING is set
ubyte Palette[PaletteSize+1][3];
-- The last entry is the delimiter color. The delimiter is not used
-- by the font but is used by imagetool when converting the font
-- back to an image. Color 0 is the transparent color and is also
-- used only for converting the font back to an image. The other
-- entries are all presorted in increasing order of brightness.
ubyte CharacterData[...];
-- RLE character data, in order
