		6	1. Postprocessing effect - wave. Ability to change amplitude and frequency.
		7	-----------------------------------------------------------------------------------
		8
		9
		10	1. Counter fix by Mario.
		11	2. New drawing model - smooth shaded lines (edges only view) by me.
		12	-----------------------------------------------------------------------------------
		13
		14
2736	leency	15	1. Two new buttons to increase and decrease brightness.
		16	-----------------------------------------------------------------------------------
		17
		18
2193	leency	19	1. Header fix by Leency.
		20	2. SSE2 optimizations by me. (Most visable in BUMP_TEX mode.)
		21	-----------------------------------------------------------------------------------
2736	leency	22
2193	leency	23
1979	yogev_ezra	24	1. Bump and pararell two texture mapping functions optimizations.
		25	(files bump_cat.inc & two_tex.inc)
		26	On my P4 changes are rather non visable, but on dual core in KlbrInWin
		27	optimizations runs preety nice.
		28	-----------------------------------------------------------------------------------
		29
		30
		31	1. Blur function optimization on SSE and SSE2 (buttons 'blur' and 'fire').
		32	-----------------------------------------------------------------------------------
		33
		34
1931	yogev_ezra	35	1. By opening file bigger then ~18 KB, and choosing env mode program terminate.
		36	I remove this bug
		37	-----------------------------------------------------------------------------------
		38
		39
		40	1. MMX optimizations in 2tex mode (file two_tex.inc).
		41	2. Tiny SSE optimizations (file BUMP_CAT.INC).
		42	3. Bit (two instructions) improved random light generation procedure.
		43	-----------------------------------------------------------------------------------
		44
		45
1819	yogev_ezra	46	1. SSE optimizations (file BUMP_TEX.INC).
		47	2. Compiles correctly in newest FASM.
		48	-----------------------------------------------------------------------------------
		49
		50
		51	1. Skinned window by Leency.
		52	2. Optimizations.
		53	3. Re map texture, bumps option - allow spherical mapping around each axle (X,Y,Z).
		54	4. Problem with too small memory to generate object fixed. (Problem ocurred with
		55	house.3ds object and others objects contains less than 1000 faces and points).
		56	-----------------------------------------------------------------------------------
		57
		58
		59	1. Optimizations.
		60	-----------------------------------------------------------------------------------
		61
		62
		63	1. Memory for file is allocated dynamically.
		64	2. Optimizations.
		65	Note: compiling correct only for KolibriOS.
		66	-----------------------------------------------------------------------------------
		67
		68
		69	1. More smooth texture mapping in tex and txgr shading model and others based on
		70	tex3.inc, tex_cat.inc shading models.
		71	2. Predefined three, I hope, nice lights.
		72	-----------------------------------------------------------------------------------
		73
		74
		75	1. New shading model: cubic environment mapping with 1.5 kb light buffer.
		76	2. Bumps optionally according to texture. ( It gives so called texture with
		77	shifts in bumps + texture shading model. )
		78	3. Bumps depth button.
		79	-----------------------------------------------------------------------------------
		80
		81
		82	1. New shading model: bump + texture. Only version with z coordinate
		83	interpolation.
		84	2. SSE optimizations ( files: two_tex.inc and bump_tex.inc )
		85	-----------------------------------------------------------------------------------
		86
		87
		88	1. Two shading models: smooth + texture, spherical environment mapping + texture.
		89	Version only with z coordinate interpolation.
		90	2. Bit changed rotary. I took attempt in SSE instuctions. ( matrix multiplication )
		91	3. Color position depend drawing model instead spot light ( I hope,spot light come
		92	back in future ).
		93	-----------------------------------------------------------------------------------
		94
		95
		96	1. New shading models - "spot" - spot light (only one, it's very CPU hungry model,
		97	and there is no easy way to implement buffer) with light attenuation (In my
		98	implmentation works not perfect); "dots" - app draws only points (with no culling).
		99	2. Some loseless operations "mirror": according to each axis, rotary 90 degrees.
		100	3. Postprocesing efects: Emboss (use blur to make edges more visable), fire ( be
		101	carefull during `fire + embos`parallel using).
		102	4. "Move" - Changes meaning of 'add vector' buttons:
		103	used "obj" move object, "camr" move camera (in this option use culling = 'off'
		104	I must make culling procedure bit advanced).
		105	5. Generate button. Few objects generating (with bad normals)
		106	6. Some optimizations on MMX.
		107	7. I took an attempt to memory managing functions, but it decreased speed (no aligned
		108	memory in Menuet functions?)
		109
		110
		111	Greetings for all, especially Madis Kalme for .3ds files support and good vibrations. ;)
		112	Merry Christmas and happy new year.
		113	-----------------------------------------------------------------------------------
		114
		115
		116	1. Object generating (for now only one). When no parameter specified or error occured
		117	during reading file from disk, app generate object. No teapot.3ds needed on ramdrive,
		118	but, if this file exist it would be read as default.
		119	2. Bug in read_from_file procedure fixed. (In May, when I made shading light vector
		120	depend, I demaged bit Madis' procedure.)
		121	3. Backface culling on/off option. (Some objects need culling off - they have mismatched
		122	normal vectors. Example: iron.3ds, sink.3ds, the generated one.)
		123	4. Random lights procedure.
		124	5. Spherical (instead old - planar ) bump, texture mapping.
		125	6. Bit improved menu.
		126	7. Blur.
		127	-----------------------------------------------------------------------------------
		128
		129
		130	Based on earlier demos.
		131	1. 3ds object import as a parameter ( for now only short names supported )
		132	I updated Kfar app - it can run view3ds with parameter. You must copy it on
		133	ramdrive. You could do such funny thing: Run updated Kfar in KolbrInWin,
		134	before them set in KolInWin.ini file path to ramdrive, where yo have "view3ds",
		135	choose 3ds file ... Emulator will run View3ds with selected file.
		136	If no parameter specified, app try open tpot.3ds from ramdrive. If tpot.3ds
		137	don't exist on rd, app hang.
		138	2. Many lights. Every light - unlinear model ( Phong illumination ). For now
		139	no light setting option.
		140	3. Light buffer for grd, flat model.
