Utility function to map a XY + Side coordinate to a direction vector

Scoring function for directional navigation. Based on https://gist.github.com/rygorous/6981057

FIXME-LEGACY: Prior to 1.61 our DragInt() function internally used floats and because of this the compile-time default value for format was "%.0f". Ev

NB: this can be called with negative count for removing primitives (as long as the result does not underflow)

When using this function it is sane to ensure that float are perfectly rounded to integer values, to that e.g. (int)(max.x-min.x) in user's render pro

FIXME-OPT: Need a way to reuse the result of lower_bound when doing GetInt()/SetInt() - not too bad because it only happens on explicit interaction (m

level may actually range from [0,10] (10 is a "hidden" max level, where we want a bit more compression and it's fine if throughput to fall off a cliff

x0/y0/x1/y1 are offset from the character upper-left layout position, in pixels. Therefore x0/y0 are often fairly close to zero. Not to be mistaken wi
