	The Gimp plug-in for msx-ize pictures.

	Built up from the example blur plug-in by David Neary 
	(http://developer.gimp.org/writing-a-plug-in/1/index.html)

	Built up from the C++ ColorSpace Library by Berendea Nicolae
	(https://github.com/berendeanicolae/ColorSpace)

	To install the plug-in in the ~/.gimp-2.x/plug-ins , close The Gimp and write in console:
	
	CC=g++ LIBS="-lm" CFLAGS="-std=c++11 -O3 -omsxize" gimptool-2.0 --install "ColorSpace.cpp Comparison.cpp Conversion.cpp objgimp.cpp objmsx.cpp msxize.cpp"

	If there is any package missing (typically libgimp-dev), you will be warned at that call.
