NAME
       gluProject - map object coordinates to window coordinates

C SPECIFICATION
       GLint gluProject(GLdouble objX, GLdouble objY, GLdouble objZ, const GLdouble * model, const GLdouble * proj, const GLint * view,
			GLdouble* winX, GLdouble* winY, GLdouble* winZ);

PARAMETERS
       objX, objY, objZ
	   Specify the object coordinates.

       model
	   Specifies the current modelview matrix (as from a glGetDoublev() call).

       proj
	   Specifies the current projection matrix (as from a glGetDoublev() call).

       view
	   Specifies the current viewport (as from a glGetIntegerv() call).

       winX, winY, winZ
	   Return the computed window coordinates.

DESCRIPTION
       gluProject transforms the specified object coordinates into window coordinates using model, proj, and view. The result is stored in winX,
       winY, and winZ. A return value of GLU_TRUE indicates success, a return value of GLU_FALSE indicates failure.

       To compute the coordinates, let v = objX objY objZ 1.0 represented as a matrix with 4 rows and 1 column. Then gluProject computes v '' as
       follows:

       v '' = P x M x v

       where P is the current projection matrix proj and M is the current modelview matrix model (both represented as 4 x 4 matrices in
       column-major order).

       The window coordinates are then computed as follows:

       winX = view  0 + view  2 x v ''	0 + 1 2.PP winY = view	1 + view  3 x v ''  1 + 1 2.PP winZ = v ''  2 + 1 2
