		4	2. New displaying model - real Phong - real not fake normal vector interpolation,
		5	normalising it and calculating dot product (one for each light).
		6	It requires SSE3. (by me, Maciej Guba)
		7	-----------------------------------------------------------------------------------

8047	leency	10	1. KPacked files support by Leency.
		11	2. 32bit vertices indexes and ability to load whole RAM limited objects.
		12	(Above 65535 vertices and triangles), (by me).
		13	3. I switch off painters algotithm mode (depth sorting). In app impelementetion it has
		14	limited vertices count and produce less quality image than Z buffer Catmull algo.
		15	In addition this switch off reduces app size, (by me).
		16	-----------------------------------------------------------------------------------
		17
		18
7280	leency	19	1. Editing option - new 'editor' button.
		20	2. For now I disable perspective correction, to make implemtation
8014	leency	21	of editing option easier.
		22	-----------------------------------------------------------------------------------
7280	leency	23

6769	IgorA	25	1. Sizable app window.
		26	-----------------------------------------------------------------------------------
		27
5486	leency	28
6769	IgorA	29	1. App window size according to current screen resolution.
6648	leency	30	2. New emboss procedure.
		31	-----------------------------------------------------------------------------------
		32
		33
6619	leency	34	1. Asc files support.
		35	-----------------------------------------------------------------------------------

		37
5486	leency	38	1. Bug fixes.
3066	leency	39	-----------------------------------------------------------------------------------
		40
		41
		42	1. Postprocessing effect - wave. Ability to change amplitude and frequency.
		43	-----------------------------------------------------------------------------------
		44
		45
		46	1. Counter fix by Mario.
		47	2. New drawing model - smooth shaded lines (edges only view) by me.
		48	-----------------------------------------------------------------------------------
		49
		50
2736	leency	51	1. Two new buttons to increase and decrease brightness.
		52	-----------------------------------------------------------------------------------
		53
		54
2193	leency	55	1. Header fix by Leency.
		56	2. SSE2 optimizations by me. (Most visable in BUMP_TEX mode.)
		57	-----------------------------------------------------------------------------------
2736	leency	58
2193	leency	59
1979	yogev_ezra	60	1. Bump and pararell two texture mapping functions optimizations.
		61	(files bump_cat.inc & two_tex.inc)
		62	On my P4 changes are rather non visable, but on dual core in KlbrInWin
		63	optimizations runs preety nice.
		64	-----------------------------------------------------------------------------------
		65
		66
		67	1. Blur function optimization on SSE and SSE2 (buttons 'blur' and 'fire').
6619	leency	68	-----------------------------------------------------------------------------------
1979	yogev_ezra	69
6619	leency	70
1931	yogev_ezra	71	1. By opening file bigger then ~18 KB, and choosing env mode program terminate.
		72	I remove this bug
		73	-----------------------------------------------------------------------------------
		74
		75
		76	1. MMX optimizations in 2tex mode (file two_tex.inc).
		77	2. Tiny SSE optimizations (file BUMP_CAT.INC).
		78	3. Bit (two instructions) improved random light generation procedure.
		79	-----------------------------------------------------------------------------------
		80
		81
1819	yogev_ezra	82	1. SSE optimizations (file BUMP_TEX.INC).
		83	2. Compiles correctly in newest FASM.
		84	-----------------------------------------------------------------------------------
		85
		86
		87	1. Skinned window by Leency.
		88	2. Optimizations.
		89	3. Re map texture, bumps option - allow spherical mapping around each axle (X,Y,Z).
		90	4. Problem with too small memory to generate object fixed. (Problem ocurred with
		91	house.3ds object and others objects contains less than 1000 faces and points).
		92	-----------------------------------------------------------------------------------
		93
		94
		95	1. Optimizations.
		96	-----------------------------------------------------------------------------------
		97
		98
		99	1. Memory for file is allocated dynamically.
		100	2. Optimizations.
		101	Note: compiling correct only for KolibriOS.
		102	-----------------------------------------------------------------------------------
		103
		104
		105	1. More smooth texture mapping in tex and txgr shading model and others based on
		106	tex3.inc, tex_cat.inc shading models.
		107	2. Predefined three, I hope, nice lights.
		108	-----------------------------------------------------------------------------------
		109
		110
		111	1. New shading model: cubic environment mapping with 1.5 kb light buffer.
		112	2. Bumps optionally according to texture. ( It gives so called texture with
		113	shifts in bumps + texture shading model. )
		114	3. Bumps depth button.
		115	-----------------------------------------------------------------------------------
		116
		117
		118	1. New shading model: bump + texture. Only version with z coordinate
		119	interpolation.
		120	2. SSE optimizations ( files: two_tex.inc and bump_tex.inc )
		121	-----------------------------------------------------------------------------------
		122
		123
		124	1. Two shading models: smooth + texture, spherical environment mapping + texture.
		125	Version only with z coordinate interpolation.
		126	2. Bit changed rotary. I took attempt in SSE instuctions. ( matrix multiplication )
		127	3. Color position depend drawing model instead spot light ( I hope,spot light come
8047	leency	128	back in future ).
1819	yogev_ezra	129	-----------------------------------------------------------------------------------
		130
		131
		132	1. New shading models - "spot" - spot light (only one, it's very CPU hungry model,
		133	and there is no easy way to implement buffer) with light attenuation (In my
		134	implmentation works not perfect); "dots" - app draws only points (with no culling).
		135	2. Some loseless operations "mirror": according to each axis, rotary 90 degrees.
		136	3. Postprocesing efects: Emboss (use blur to make edges more visable), fire ( be
		137	carefull during `fire + embos`parallel using).
		138	4. "Move" - Changes meaning of 'add vector' buttons:
		139	used "obj" move object, "camr" move camera (in this option use culling = 'off'
		140	I must make culling procedure bit advanced).
		141	5. Generate button. Few objects generating (with bad normals)
		142	6. Some optimizations on MMX.
		143	7. I took an attempt to memory managing functions, but it decreased speed (no aligned
		144	memory in Menuet functions?)
		145
		146
		147	Greetings for all, especially Madis Kalme for .3ds files support and good vibrations. ;)
		148	Merry Christmas and happy new year.
		149	-----------------------------------------------------------------------------------
		150
		151
		152	1. Object generating (for now only one). When no parameter specified or error occured
		153	during reading file from disk, app generate object. No teapot.3ds needed on ramdrive,
		154	but, if this file exist it would be read as default.
		155	2. Bug in read_from_file procedure fixed. (In May, when I made shading light vector
		156	depend, I demaged bit Madis' procedure.)
		157	3. Backface culling on/off option. (Some objects need culling off - they have mismatched
		158	normal vectors. Example: iron.3ds, sink.3ds, the generated one.)
		159	4. Random lights procedure.
		160	5. Spherical (instead old - planar ) bump, texture mapping.
		161	6. Bit improved menu.
		162	7. Blur.
		163	-----------------------------------------------------------------------------------
		164
		165
		166	Based on earlier demos.
		167	1. 3ds object import as a parameter ( for now only short names supported )
		168	I updated Kfar app - it can run view3ds with parameter. You must copy it on
		169	ramdrive. You could do such funny thing: Run updated Kfar in KolbrInWin,
		170	before them set in KolInWin.ini file path to ramdrive, where yo have "view3ds",
		171	choose 3ds file ... Emulator will run View3ds with selected file.
		172	If no parameter specified, app try open tpot.3ds from ramdrive. If tpot.3ds
		173	don't exist on rd, app hang.
		174	2. Many lights. Every light - unlinear model ( Phong illumination ). For now
		175	no light setting option.
		176	3. Light buffer for grd, flat model.
