		10	1. Postprocessing effect - wave. Ability to change amplitude and frequency.
		11	-----------------------------------------------------------------------------------
		12
		13
		14	1. Counter fix by Mario.
		15	2. New drawing model - smooth shaded lines (edges only view) by me.
		16	-----------------------------------------------------------------------------------
		17
		18
2736	leency	19	1. Two new buttons to increase and decrease brightness.
		20	-----------------------------------------------------------------------------------
		21
		22
2193	leency	23	1. Header fix by Leency.
		24	2. SSE2 optimizations by me. (Most visable in BUMP_TEX mode.)
		25	-----------------------------------------------------------------------------------
2736	leency	26
2193	leency	27
1979	yogev_ezra	28	1. Bump and pararell two texture mapping functions optimizations.
		29	(files bump_cat.inc & two_tex.inc)
		30	On my P4 changes are rather non visable, but on dual core in KlbrInWin
		31	optimizations runs preety nice.
		32	-----------------------------------------------------------------------------------
		33
		34
		35	1. Blur function optimization on SSE and SSE2 (buttons 'blur' and 'fire').
6619	leency	36	-----------------------------------------------------------------------------------
1979	yogev_ezra	37
6619	leency	38
1931	yogev_ezra	39	1. By opening file bigger then ~18 KB, and choosing env mode program terminate.
		40	I remove this bug
		41	-----------------------------------------------------------------------------------
		42
		43
		44	1. MMX optimizations in 2tex mode (file two_tex.inc).
		45	2. Tiny SSE optimizations (file BUMP_CAT.INC).
		46	3. Bit (two instructions) improved random light generation procedure.
		47	-----------------------------------------------------------------------------------
		48
		49
1819	yogev_ezra	50	1. SSE optimizations (file BUMP_TEX.INC).
		51	2. Compiles correctly in newest FASM.
		52	-----------------------------------------------------------------------------------
		53
		54
		55	1. Skinned window by Leency.
		56	2. Optimizations.
		57	3. Re map texture, bumps option - allow spherical mapping around each axle (X,Y,Z).
		58	4. Problem with too small memory to generate object fixed. (Problem ocurred with
		59	house.3ds object and others objects contains less than 1000 faces and points).
		60	-----------------------------------------------------------------------------------
		61
		62
		63	1. Optimizations.
		64	-----------------------------------------------------------------------------------
		65
		66
		67	1. Memory for file is allocated dynamically.
		68	2. Optimizations.
		69	Note: compiling correct only for KolibriOS.
		70	-----------------------------------------------------------------------------------
		71
		72
		73	1. More smooth texture mapping in tex and txgr shading model and others based on
		74	tex3.inc, tex_cat.inc shading models.
		75	2. Predefined three, I hope, nice lights.
		76	-----------------------------------------------------------------------------------
		77
		78
		79	1. New shading model: cubic environment mapping with 1.5 kb light buffer.
		80	2. Bumps optionally according to texture. ( It gives so called texture with
		81	shifts in bumps + texture shading model. )
		82	3. Bumps depth button.
		83	-----------------------------------------------------------------------------------
		84
		85
		86	1. New shading model: bump + texture. Only version with z coordinate
		87	interpolation.
		88	2. SSE optimizations ( files: two_tex.inc and bump_tex.inc )
		89	-----------------------------------------------------------------------------------
		90
		91
		92	1. Two shading models: smooth + texture, spherical environment mapping + texture.
		93	Version only with z coordinate interpolation.
		94	2. Bit changed rotary. I took attempt in SSE instuctions. ( matrix multiplication )
		95	3. Color position depend drawing model instead spot light ( I hope,spot light come
6619	leency	96	back in future ).
1819	yogev_ezra	97	-----------------------------------------------------------------------------------
		98
		99
		100	1. New shading models - "spot" - spot light (only one, it's very CPU hungry model,
		101	and there is no easy way to implement buffer) with light attenuation (In my
		102	implmentation works not perfect); "dots" - app draws only points (with no culling).
		103	2. Some loseless operations "mirror": according to each axis, rotary 90 degrees.
		104	3. Postprocesing efects: Emboss (use blur to make edges more visable), fire ( be
		105	carefull during `fire + embos`parallel using).
		106	4. "Move" - Changes meaning of 'add vector' buttons:
		107	used "obj" move object, "camr" move camera (in this option use culling = 'off'
		108	I must make culling procedure bit advanced).
		109	5. Generate button. Few objects generating (with bad normals)
		110	6. Some optimizations on MMX.
		111	7. I took an attempt to memory managing functions, but it decreased speed (no aligned
		112	memory in Menuet functions?)
		113
		114
		115	Greetings for all, especially Madis Kalme for .3ds files support and good vibrations. ;)
		116	Merry Christmas and happy new year.
		117	-----------------------------------------------------------------------------------
		118
		119
		120	1. Object generating (for now only one). When no parameter specified or error occured
		121	during reading file from disk, app generate object. No teapot.3ds needed on ramdrive,
		122	but, if this file exist it would be read as default.
		123	2. Bug in read_from_file procedure fixed. (In May, when I made shading light vector
		124	depend, I demaged bit Madis' procedure.)
		125	3. Backface culling on/off option. (Some objects need culling off - they have mismatched
		126	normal vectors. Example: iron.3ds, sink.3ds, the generated one.)
		127	4. Random lights procedure.
		128	5. Spherical (instead old - planar ) bump, texture mapping.
		129	6. Bit improved menu.
		130	7. Blur.
		131	-----------------------------------------------------------------------------------
		132
		133
		134	Based on earlier demos.
		135	1. 3ds object import as a parameter ( for now only short names supported )
		136	I updated Kfar app - it can run view3ds with parameter. You must copy it on
		137	ramdrive. You could do such funny thing: Run updated Kfar in KolbrInWin,
		138	before them set in KolInWin.ini file path to ramdrive, where yo have "view3ds",
		139	choose 3ds file ... Emulator will run View3ds with selected file.
		140	If no parameter specified, app try open tpot.3ds from ramdrive. If tpot.3ds
		141	don't exist on rd, app hang.
		142	2. Many lights. Every light - unlinear model ( Phong illumination ). For now
		143	no light setting option.
		144	3. Light buffer for grd, flat model.
