	* libgimpcolor/gimprgb-parse.c
	* libgimpcolor/gimprgb.h: use a signed integer to pass the string
	length to the new parser functions. The API explicitely asks for
	-1 to be passed...

	* app/core/gimp.c
	* app/core/gimpgradient-load.[ch]
	* app/core/gimpgradient.h: added preliminary support for loading
	simple SVG gradients (see bug #148127).  Be careful with this new
	feature; editing the loaded gradient will cause the SVG file to be
	overwritten! Work in progress...
