-- GLscreen -------------------------------------------------------------------------------------------------------------

GLsetdisplay(w,h,bpp,mode)	: open the sdldisplay in opengl blit mode (0 full screen | 1 windows 2 resizable
GLscreenswap()			: swap the buffers of display
GLscreen2D(m)			: enable(1) disable(0) the updating of 2d sdl screen in GLdisplay
GLscreenrect (x,y,w,h)		: define the glviewport

-- GLcamera -------------------------------------------------------------------------------------------------------------
GLcameraposition(x,y,z)		: set the position of camera
GLcameraangle(x,y,z)		: set the angle where point camera
GLcameralook(x,y,z)		: the camera point at xyz coords in space

-- GLlight --------------------------------------------------------------------------------------------------------------
*GLmakelight(n,x,y,z,r,g,b,pow)

-- GLgraphics ------------------------------------------------------------------------------------------------------------
GLcolor(r,g,b)			: set the current opengl color in format rgb

-- GLtexture ------------------------------------------------------------------------------------------------------------
GLloadtexture(file,n)		: load a texture in a buffer n
GLmaketexture(n,m)		: make sdlimage n in a textur in buffer n : m is a method of create texture
GLtexture(n)			: set the texture n

-- GLobject -------------------------------------------------------------------------------------------------------------
Glmakecube(x,y,z,size)		: make a cube object
Glmakesphere(x,y,z,size)	: make a sphere (texture not work)
GLmakesurface(v1,v2,v3,v4)	: make a rectangular surface with a texture (v1 v2 v3 v4 are vertexs)

-- GLmatrix -------------------------------------------------------------------------------------------------------------

GLbegin(type)			: start a drawing matrix type can be triangle qads etc.
GLend				: terminate a drawing matrix
GLtexcoord(x,y)			: set point of a surface texturable
GLsetvertex(v OR x,y,z)		: set a matrix vertex
GLnormal(x,y,z)			:
GLpushmatrix			:
GLpopmatrix			:
GLflush				:

-- GLlowlevel -----------------------------------------------------------------------------------------------------------

GLvertex (n,x,y,z)		: set the vertex array n
GLtranslate (x,y,z)		: move the matrix
GLrotate(ang,x,y,z)		: rotate the matrix
GLenable(param)			: enable feature
