This code was not tested and breaks in Release builds, reverting to restore
functionality of the nightly. All in-game menus do not work and generating
a world crashes.
This reverts commit a9be52c41a.

|

//available for a particular output device.

//Parameters:
|
|
//r - the red component
|
|
//g - the green component
|
|
//b - the blue component

//Throws:

//IllegalArgumentException - if r, g or b are outside of the range 0.0 to 1.0, inclusive
