//
// IMPORTANT INFORMATION ABOUT MODES
//
// - Mode 1 is slightly faster than mode 2
// - Mode 2 is slightly faster than mode 3
// - Mode 1 can only be used in ASE
// - Modes 2 and 3 can be used in ASE or in AFRYCA plug-ins source code
// - Modes 1 and 2 fail if the engine is not loaded
// - Mode 3 return null if the engine is not loaded
