##########################################################
How to use it :
put prgmGCORE in the header of your program. This is the
main librairy.

warning : don't use L1

##########################################################

	MAIN LIB : GCORE LIB

###########################################################
#GLOBAL VARS -- GCORE LIB#

GVAdr : this is the adresse of your liste of vertex
GVStr : free area to store the rotate vertex. Make sure 
it's a 6*NB_VERTEX weight area

#ENVIRONNENMENT VARS -- GCORE LIB#

environnements vars is some constants who change the
effect of some routine. Make sure you put this before
the line :prgmGCORE

°GCamera :camera mode
0:fps mode
1:object visualisation mode, distance camera-object can
change
2:same as above, but with constant distance D=128
Default : 0

°GNear : distance of the clipping plane and the camera
Can take all value. 
Default : 8 (8 is a good valu to eliminate most of
rendering error.

°GhlSpac2Scr : value that the GSpac2Scr commands should
return, more explanation in the GSpac2Scr command field
defaukt : 6

°GJumpXY,°GJumpZ : angle the camera should rotate. XY is
for "horizontal roation", Z for the "vertical"
Default : depend on the camera mode

#ONLY IN GCAMERA=1#

°GDMin, °GDMax : the maximun and the minimum distance
in wich the camera can move.

#COMMANDS -- GCORE LIB#
###########################################################
GInit()
initialisation of the 3d processing
return : none
###########################################################
GGetkey()
handle all the good getkey, corresponding with the
°GCamera mode
directionnals keys: rotation, deplacement
mode/del : Z rotation
F1/F5 : zoom/dezoom, camera distance
return : none
###########################################################
GSpac2Spac(°FREE,X,Z,Y
process the 3d rotation and store the rotated point in
°FREE
format : {°FREE}^^r=X
	 {°FREE+2}^^r=Y
	 {°FREE+4}^^r=Z
return : °FREE+4 adresse
###########################################################
GSpac2Scr(°FREE,X,Z,Y)
process the 3d rotation, and calculate the 2D position
on screen. Store it in °FREE
format : {°FREE}^^r=X    ;2D position
	 {°FREE+2}^^r=Y  ;2D position
	 {°FREE+4}^^r=Z  ;3D distance camera-point
return : °FREE+°GhlSpac2Scr
you can choose if the command return °FREE+0, °FREE+2...
#############################################################
G3dTo2D(°FREE)
caculate the 2d coordinate of a 3d point.
format : input :
{°FREE}^^r=X
{°FREE+2}^^r=Y
{°FREE+4}^^r=Z
output :
{°FREE}^^r=X   ;2D coordinate
{°FREE+2}^^r=Y ;2D coordinate
{°FREE+4}^^r=Z ;the same value
##############################################################
GCLine(X,Y,X2,Y2
Draw a cliped line beetwen X,Y and X2,Y2
return : none
##############################################################
GClipLine(VERTEX_ID,VERTEX2_ID)
draw a complete cliped line against the °GNear plane and the screen
Vertex should be store at GVStr, and GVAdr
make sure vertex are store each 6 bytes in GVStr
##############################################################
GCode(X,Y)
compute the outccode for the X,Y coordinate
(subroutine, don't actually use it)
###############################################################
#DATA STRUCTURE -- GCORE LIB#

GVAdr structure:
Data(X,Z,Y)->GVADr
X,Y,Z  are 1 byte value

GVStr structure :
Store the rotated  vertex each 6 bytes, in correpondance with
their position in GVAdr
