/****************************************************
Audio Patterns
These are the various pattern functions, except
for StarBurst which is a separte file. Patterns base on
the "noise" function have issues with SM4.
The life pattern currently consumes too much memory
on displays larger than 128x128 so theres a #define
to inclue it.
conversion to SmartMatrix 4 continues...
with rotation capability, new defs, example for 128x128 display
matrix.getScreenWidth() num horizontal pixels (128)
getScreenHeight() num vertical pixels (128)
kScreenWidth = matrix.getScreenWidth() - 1; matrix indexing (127)
kScreenHeight = matrix.getScreenHeight() - 1 ; matrix indexing (127)
kMatrixCenterX = kScreenWidth / 2; horizontal center (63)
kMatrixCenterY = kScreenHeight / 2; vertical center (63)
