// -------------------------------------------------------------------------------------------
// History :
// 2016/09/11 Behind camera culling. Scaling Delta matrix not multiplied by source matrix scales. local/world rotation and translation fixed. Display message is incorrect (X: ... Y:...) in local mode.
// 2016/09/09 Hatched negative axis. Snapping. Documentation update.
// 2016/09/04 Axis switch and translation plan autohiding. Scale transform stability improved
// 2016/09/01 Mogwai changed to Manipulate. Draw debug cube. Fixed inverted scale. Mixing scale and translation/rotation gives bad results.
// 2016/08/31 First version
//
// -------------------------------------------------------------------------------------------
// Future (no order):
//
// - Multi view
// - display rotation/translation/scale infos in local/world space and not only local
// - finish local/world matrix application
// - OPERATION as bitmask
//
// -------------------------------------------------------------------------------------------
// Example
