SCT file format (TA sections)
Written by Kinboat, 1998.
*****************************

** Note **
In order for these sections to work in TAE, their dimensions must be
a multiple of 128.

** File Header (28 bytes) *)
typedef struct _SCTHEADER {
  long Version;		// SCT Version.  Set to 3.
  long PtrMinimap;	// Offset to the section's minimap.
  long NumTiles;	// The number of tiles in the section.
  long PtrTiles;	// Offset to the section's tiles.
  long Width;		// Width of the section.
  long Height;		// Height of the section.
  long PtrData;		// Offset to the section's data.
} SCTHEADER;


** TileData (PtrTiles) **
Each tile is 32x32 pixels.

BYTE TileData[NumTiles * 1024];


** SectionData (PtrSectionData) **
short SectionData[SectionWidth*SectionHeight];
  This array is an array of index values pointing to tiles stored in 
  the TileData.

typedef struct _HEIGHTDATA {
  BYTE Height;		// Height value.
  short Constant1;	// Always -1.
  BYTE Constant2;	// Always 0.
} HEIGHTDATA;

HEIGHTDATA HeightData[SectionWidth * SectionHeight * 4]
  This is an array to the 3D height data for the section.  Each tile
  pointed to by SectionData has 4 height values.


** Minimap (PtrMinimap) **
BYTE Minimap[128 * 128];
