Detailed Description

template<typename T>
class ml::LUTIterator< T >

The LUTIterator class template is used by a LUTFunction object for rendering into a LUTData object.

For each lookup index, the LUT uses the channel pointers chn to store the LUT entry values, and calls the LUTIterator's increment operator to convert the entry values into the type of the LUTData object (if necessary) and to increment the channel data pointers.
