// Update 13/09/2017 - It seems that the console behaves differently on some systems
// and I'm unsure why this is. It could be to do with windows default settings, or
// screen resolutions, or system languages. Unfortunately, MSDN does not offer much
// by way of useful information, and so the resulting sequence is the reult of experiment
// that seems to work in multiple cases.
//
// The problem seems to be that the SetConsoleXXX functions are somewhat circular and
// fail depending on the state of the current console properties, i.e. you can't set
// the buffer size until you set the screen size, but you can't change the screen size
// until the buffer size is correct. This coupled with a precise ordering of calls
// makes this procedure seem a little mystical :-P. Thanks to wowLinh for helping - Jx9
