June 31, 2000:  Started changelog.  

Current status:  

	-BasicTexture works, but should be subclassed by texture 
	functions / extensions.  
	-Parameter linking works.  
	-Tree doesn't support any channels but color.
	-Mapping may not need to exist.  BasicTexture may be the only sort of 
	texture needed.  Thus, subclassing Texture would be unnecessary - 
	there would be only one sort of texture.  The reason for subclassing 
	(and classes like mapping) initially was that I had only seen a 
	screenshot of darktree, and didn't grok parameter linking - I assumed 
	it was done slightly differently.  Parameter linking is more 
	intuitive (code and UI wise) than my original code.  Am I wrong?

July 7, 2000:

	-Changed class heirarchy around massively.  All textures are now subclasses of BasicTexture.  
	-Each basic texture now has its own class.  Still need to convert mappings and composite textures to this new system.


July 9, 2000:

	-Started loader for DarkTree files.  This distribution now has one darktree shader for testing: Eye_KillerIris.dst.  
	-Tons of DarkTree shaders can be found through:
	http://www.darksim.com/Repository/dtrep.zip
	-The loader doesn't do much yet... It's pretty clear that we'll have to write a new one eventually using lex (GNU: flex) and maybe YACC (GNU: bison). 
	-To continue the loader, I need a BasicTexture factory method.  I will write one for the next release.
