must be multiples of 4 though, and no mipmaps can be generated.

Added a YCoCg scaled compression format. It's the same as normal YCoCg,
except with extra color precision stored in the blue bits. Use YCoCg for
high quality with alpha stored in the blue channel at the cost of some color
precision, and YCoCg scaled for the highest color precision without alpha.

* 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.

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.
