The Palette type allows the application to redefine the colors being used and
allow for index colors to be used instead of RBG values in images.

PLTT Structure

The following values are used through this and all of my file definitions
unless otherwise specified:
NAME	LENGTH	DESC
----	------	----
BYTE	1	unsigned 8-bit
CHAR	1	ASCII character
INT	4	signed Int32

--
0x00	Header
0x10	BYTE	StartIndex
0x11	BYTE	EndIndex
0x12	Color[EndIndex-StartIndex+1]
	BYTE	Reserved (0)
--

struct Header (size 0x10)
{
	0x0	CHAR[4]	"PLTT"
	0x4	CHAR[8]	Name
	0xC	INT	Length
}

struct Color (size 0x3)
{
	0x0	BYTE	Red
	0x1	BYTE	Green
	0x2	BYTE	Blue
}

PLTT Detail

The StartIndex defines the first ColorIndex that Color values are given for.
The EndIndex likewise defines the last ColorIndex that is being defined. For
example, the palette for the Battle Selection screen is defined in TOURDESK.LFD
and begins at StartIndex 0x20 and runs through EndIndex 0xFF. Thus, the first
Color value defines ColorIndex 0x20 which will be shown anywhere 0x20 is called
as a ColorIndex.

The Color values are simply RGB values ranging from 0x00 to 0xFF.

The typical values for the beginning range appear to be the standard 16 colors
for 0x00 to 0x0F, with greyscale values for 0x10 to 0x1F as defined in
EMPIRE.LFD.
