The look-up table related variables are merged in a new structure
named LUT%. See table for details. This
structure has three major groups of variables related to the images
look-up table (under LUT%), to the blanking color (under LUT%BLANKING%) and to the pen look-up table (under LUT%PEN%).
The variables describing the current RG image plotted by the command GREG2PLOT are merged under the structure CURIMA%. The equalization mode, if in use, is described under the substructure CURIMA%EQUAL%. See table for details.
