/**
 * The base toolkit class for MS-JVM JDirect calls !
 *
 * The methods in this class are used by gl4java.GLContext !
 * Because this class MUST compiled with the MS-JVM Java Compiler
 * I have decided to put it out of gl4java.GLContext,
 * although this can be a security hole ...
 * But we must be able to use GL4Java without MS-JVM bytecode.
 *
 * The Tag @security(checkDllCalls=off) makes us able to
 * use these methods outside of these class,
 * without a security check all the time.
 * The security check is performed at link-time !
 * 
 * This is the same for gl4java.GLUFuncMSJDirect
 * and gl4java.GLFuncMSJDirect !
 *
 * @see gl4java.GLContext
 * @version 	1.00
