## To Do List
* YUV
* Gamma adjustment modification
* Auto-gamma adjustment and conversion for rec709, rec2020, and jpeg to/from ypbpr
* note to self: rec709 does gamma conversion before while rec2020 does gamma conversion after when converting to ypbpr (I think)
* Write more documentation wrt mathematics.
* Integrate my references better. :)
