The table of named colors has been compressed and moved out from Quantity_Color.cxx into Quantity_ColorTable.pxx. Quantity_NameOfColor - grayscale enumeration values have been re-ordered to fix discontinuity. Duplicating colors has been merged within enumeration: CHARTREUSE=CHARTREUSE1, GOLD=GOLD1, GREEN=GREEN1, ORANGE=ORANGE1, ORANGERED=ORANGERED1, RED=RED1, TOMATO=TOMATO1, YELLOW=YELLOW1. Added aliases to several other common colors: BLUE=BLUE1, CYAN=CYAN1, LIGHTCYAN=LIGHTCYAN1, MAGENTA=MAGENTA1. Quantity_Color class definition has been cleaned to follow OCCT coding style. Quantity_Color now stores NCollection_Vec3<float> as class field instead of separate components. Removed unused class Quantity_ColorDefinitionError. New methods Quantity_Color::Convert_LinearRGB_To_sRGB() and Quantity_Color::Convert_sRGB_To_LinearRGB() converting RGB components from linear to non-linear sRGB colorspace and vice versa. Image_PixMap::PixelColor() and Image_PixMap::SetPixelColor() methods have been extended with an optional argument for performing linearization/delinearization of 8-bit sRGB pixel formats. Draw Harness command AISColor has been corrected to take color name instead of enumeration index.
