* When reading compressed images, zero out destination buffer and fill alpha
channel with full opacity before decompressing. This is mainly for 3Dc
compressed images, as the blue channel should be zero and the alpha channel
fully opaque.
* Some more cleanup for 3Dc compression

* Moved the endian-safe memory to integer casting macros out of ddsplugin.h and into newly created file endian.h
* Added optional software decompression routines to dxt.c. Compression routines to follow shortly...
* Various code cleanups and Makefile modifications

* Added support for writing volume map mipmap chains for indexed images (not very good ATM)
* Pre-convert indexed images to RGB for better quality mipmaps if a pixel format conversion is requested

- Added proper read support for 8-bit paletted images. They are now read
into an indexed gimp image.
- Added write support for indexed images

* Added L8 and L8A8 pixel formats
* Fixed all pixel formats when writing images. All images saved with the
plugin should be compatible with various DDS tools out there (tested with
the DirectX DDS viewer, and nVidia's image converter)

It seems there are a lot of DDS images out there that don't have the
DDSD_PITCH or DDSD_LINEARSIZE flags set. And further, have 0 in the
pitch/linear size field of the header. This goes against the DDS image
standards. But since the problem seems so common, I've decided to demote
the DDSD_PITCH or DDSD_LINEARSIZE error to a warning, and assume DDSD_PITCH
for uncompressed images and DDSD_LINEARSIZE for DXT compressed images.
Further, if the pitch/linear size is 0, I attempt to calculate it based on
the width and height and pixel format read from the header. This should
allow the plugin to open a lot of files it previously couldn't. So much for
standards :)

A few more fixes:
* Fixed grayscale and gray-alpha loading for REAL this time.
* Disable compression for volume maps (for now...)
* Fixed mipmap saving (oops!)

Gearing up for the next release with a slug of new features:
* Added support for writing grayscale and gray-alpha images
* Added support for writing cube maps (Image must have 6 layers,
all the same size and pixel format. Cube faces controlled by layer name
contents, see documentation.)
* Added support for writing volume maps (Image must have > 1 layer,
all the same size and pixel format). Volume map compression is currently
not supported. Mipmap support is scetchy ATM. If your image's layer count
is a power of two and the image dimensions are a power of two, everything
should work fine using SGIS_generate_mipmap. If your layer count or image
dimensions are not a power of two, then mipmap generation will likely fail
unless your video card supports ARB_texture_non_power_of_two. A fix for
this will soon follow.
* Fixed volume map loading
* Cleaned up layer naming convention when loading images with mipmaps or
multiple layers (cube and volume maps)

Added feature to swap red and alpha channels on save. This helps preserve
quality when saving normal maps in compressed DXT5 format.
