* Added advanced options to save dialog to allow choice of the color
selection algorithm used in the DXT compressor, as well as whether or not to
operate on dithered blocks.
* Added distance, luminance and inset bounding box color selection
algorithms to DXT compressor.
* Updated non-interactive interface to allow use of new advanced options

* Moved OpenGL specific code to opengl.c
* Finished new compression backend. Now fully in portable ANSI C code, no
longer needs OpenGL to do compression/decompression, removes requirement for
the external DXTn compression library for software compression.

* Removed dependence on the SGIS_generate_mipmap extension. It will only be used if it is available.
* Cleaned up mipmap generation code

* 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

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)
