(2nd Draft)

Format for images in BATTLE:

Size and offset are both in bytes.  MSB is first, then LSB.  So conversions
may have to take place (intel platforms).

    Size        |   Offset      |  Description
     1          |     0         |  A byte containing the number of Bits per pixel
     1          |     1         |  1 for truecolor (grayscale or color)
                                   0 for palette based
     4          |     2         |  DWORD containing horizontal size
     4          |     6         |  DWORD containing vertical size
     n          |     10        |  Raster data (see below)
     768        |     10 + n    |  Palette data (see below)

Raster data is store as:

8bpp Palette
------------

    The image will be stored as a series of raster lines.  Each pixel
is represented by one byte.  This byte is used as an index into the palette
data.  Images are stored Top-Down (not bottom-up like BMP files).

8bpp Grayscale
--------------

    The image will be stored as a series of raster lines.  Each pixel is
represented by one byte.  This byte is used as the gray level.  A value
of 255 is white, and a value of 0 is black.  There is no palette
data stored after a grayscale image


24bpp Color
-----------

    The image will be stored as a series of raster lines.  Each pixel
is represented by three bytes.  One byte for red, green and blue intensities
(in that order).  A value of 255 is full (red, green or blue) and a value
of 0 is no intensity.  There is no palette data stored after a 24bpp color
image.


Palette Data
------------

    The palette data is stored as an array of 256 three byte triplets.  For
each of the 256 possible colors there are 3 bytes, one for red, green and
blue (in that orer).  Like 24bpp color, a value of 255 is full intensity
and 0 is no intensity.

    These palette values may have to be scaled down to work with some
hardware.  For example for the VGA you will have to divide by 4 for each
intensity.
