			davidedmundsonUnsubmitted Done so we have 3 arrays of size m_gammaSize we can pass the GammaRamp object and do: gammaRamp.red, gammaRamp.green, gammaRamp.blue, also it'll be safer to use the gammaSize from the gammaramp. otherwise if it changes, you're going to crash. if you are trying for separation pass 3 uints instead of doing pointer maths. davidedmundson:* so we have 3 arrays of size m_gammaSize we can pass the GammaRamp object and do: gammaRamp.
