Experimental Ghost_CanMoveAtAngle()

//Experimental canmoe functions for 2.8.x

// The maths here depend on if the Ghost_Step is in full pixels per frame
// or if it isPixels per frame * 100.//e.g., IDR if it is 100 for one pixel/frame using Ghost_Step, or 1.0

// Basic model for imprecision, assuming that step is an integer (e.g. 250 == 2.5 pixels per frame), as in the Enemy Editor
// If step is a float as in the engine (type 'fix' there), then we need to remove the *0.01
