OK, no need to get angry.

Idea is to allow storing of additional informations per pixel in new file 
format. 
Format would be:

V,W,H
Names
Pixel00;Pixel01;Pixel02;...Pixel0W;
...
PixelH0;PixelH1;PixelH2,...PixelHW;

V is format version like 100 W=Width H=Height

Names is list of variables names stored for each pixel i.e.
R,G,B

mean that each pixel has standard RGB information ets.

Suggested informations:

R (G,B) - red channel of output pixel 0 - 255
r (g,b) - -||- as float  0.0 - 1.0
R2 (G2,B2) - -||- as 16 bit 0 - 65536
x,y,z      - position of pixel(*) in scene relative to camera
xa,ya,za   - -||- absolute
nf,nt      - normal of surface in that point defined by 2 angles

(*) pixel - in case of AA, or focal blur - this would be the i.e. first 
sub-pixel used for computing this pixel

user1,user2,user3 - user date, user can use them in code as additional 
pigment or texture data
  pigment { bozo ...  
    info { user1 1.0, user2 2.0 }
  }

flags - user falgs - list of flags that are ON for this pixel 
  pigment { ... 
    flags { backgr, skin }
  }


It would be very usefull for game developers. I will try to create a small 
example why would I suggest thist patch in few days.

And to summ it up example of output image:

100,3,3
R,G,B,user1,flags
0,0,255,0,[backgr] 128,0,0,0,[] 0,0,255,0,[backgr]
200,0,0,1,[skin] 200,50,0,2,[skin eye] 200,0,0,1,[skin]
0,0,255,0,[backgr] 128,0,0,0,[skin] 0,0,255,0,[backgr]

and this image describes a hmm monster with in asciiart could look like

   "
  (*)   (an alien "cyclope" with eye in middle)
   A

and image is ready-to-use in game because it stores data about
- hit points for each area (user1)
- background (flags: backgr)
- monster skin where can it be hit (flags: skin)
- monster eye - from where can it attac by his thunders ;) (flags: eye)
