Vectors, positions, rectangles etc.

Modules

MovementTracker	This struct tracks recent values of some time series. This can be used for things like smoothed averages (for e.g. FPS) or for smoothed velocity (e.g. mouse pointer speed). All times are in seconds.
Pos2	A position on screen.
Rect	A rectangular region of space.
Vec2	A size or direction in 2D space.

TAU	The circumference of a circle divided by its radius.

almost_equal	Should return true when arguments are the same within some rounding error. For instance `almost_equal(x, x.to_degrees().to_radians(), f32::EPSILON)` should hold true for all x. The `epsilon` can be `f32::EPSILON` to handle simple transforms (like degrees -> radians) but should be higher to handle more complex transformations.
clamp	Returns `range.start()` if `x <= range.start()`, returns `range.end()` if `x >= range.end()` and returns `x` elsewhen.
ease_in_ease_out	For t=[0,1], returns [0,1] with a derivate of zero at both ends
format_with_minimum_precision
lerp	Linear interpolation.
pos2
remap	Linearly remap a value from one range to another, so that when `x == from.start()` returns `to.start()` and when `x == from.end()` returns `to.end()`.
remap_clamp	Like `remap`, but also clamps the value so that the returned value is always in the `to` range.
round_to_precision	Round a value to the given number of decimal places.
round_to_precision_f32	Round a value to the given number of decimal places.
