ARToolkit OpenGL subroutines.

This file contains the main display functions used in ARToolkit Library. It contains wrapped functions of GLUT and openGL for doing real-time rendering. This choice give us a large multi-platform support for the display module of ARToolkit.

transform ARToolKit intrinsic camera parameters matrix format to an openGL matrix format.
<p>
XXXBK: not be sure of this function: this function must just convert 3x4 matrix to classical perspective openGL matrix. But in the code, you used arParamDecompMat that seem decomposed K and R,t, aren't it ? why do this decomposition since we want just intrinsic parameters ? and if not what is arDecomp ?
<p>
Returned value is generally use with a Projection Matrix.
