/**
 * The following expressions are available to use in most parameters:
 *
 * ## variables
 *
 * - $F: current frame
 * - $T: current time
 * - $CH: current param name
 * - $CEX: input centroid x component
 * - $CEY: input centroid y component
 * - $CEZ: input centroid z component
 *
 * Those variables are aliases to the javascript math module:
 *
 * - $E
 * - $LN2
 * - $LN10
 * - $LOG10E
 * - $LOG2E
 * - $PI
 * - $SQRT1_2
 * - $SQRT2
 *
 * ## math expressions
 *
 * The following are native javascript functions:
 *
 * - abs
 * - acos
 * - acosh
 * - asin
 * - asinh
 * - atan
 * - atan2
 * - atanh
 * - ceil
 * - cos
 * - cosh
 * - exp
 * - expm1
 * - floor
 * - log
 * - log1p
 * - log2
 * - log10
 * - max
 * - min
 * - pow
 * - random (which aliases to Math.rand())
 * - round
 * - sign
 * - sin
 * - sinh
 * - sqrt
 * - tan
 * - tanh
 *
 * If you are targetting ES6 (available in modern browsers), you can also have:
 *
 * - cbrt
 * - hypot
 * - log10
 * - trunc
 *
 * The following are aliases from the [Polygonjs CoreMath](https://github.com/polygonjs/polygonjs-engine/blob/master/src/core/math/_Module.ts) module:
 *
 * - fit
 * - fit01
 * - fract
 * - deg2rad
 * - rad2deg
 * - rand
 * - clamp
 *
 * And the following are alias to the [Polygonjs Easing](https://github.com/polygonjs/polygonjs-engine/blob/master/src/core/math/Easing.ts) module:
 *
 * - linear
 * - ease_i
 * - ease_o
 * - ease_io
 * - ease_i2
 * - ease_o2
 * - ease_io2
 * - ease_i3
 * - ease_o3
 * - ease_io3
 * - ease_i4
 * - ease_o4
 * - ease_io4
 * - ease_i_sin
 * - ease_o_sin
 * - ease_io_sin
 * - ease_i_elastic
 * - ease_o_elastic
 * - ease_io_elastic
 *
 *
 * ## string expressions:
 *
 * - precision (alias to the [CoreString](https://github.com/polygonjs/polygonjs-engine/blob/master/src/core/String.ts) module precision method)
 * - [strCharsCount](/docs/expressions/strCharsCount)
 * - [strConcat](/docs/expressions/strConcat)
 * - [strIndex](/docs/expressions/strIndex)
 * - [strSub](/docs/expressions/strSub)
