/*******************************************************************************************
*
* reasings - raylib easings library, based on Robert Penner library
*
* Useful easing functions for values animation
*
* This header uses:
* #define REASINGS_STATIC_INLINE // Inlines all functions code, so it runs faster.
* // This requires lots of memory on system.
* How to use:
* The four inputs t,b,c,d are defined as follows:
* t = current time (in any unit measure, but same unit as duration)
* b = starting value to interpolate
* c = the total change in value of b that needs to occur
* d = total time it should take to complete (duration)
*
* Example:
*
* int currentTime = 0;
* int duration = 100;
* float startPositionX = 0.0f;
* float finalPositionX = 30.0f;
* float currentPositionX = startPositionX;
*
* while (currentPositionX < finalPositionX)
* {
* currentPositionX = EaseSineIn(currentTime, startPositionX, finalPositionX - startPositionX, duration);
* currentTime++;
* }
*
* A port of Robert Penner's easing equations to C (http://robertpenner.com/easing/)
