	* libgimptool/gimptoolcontrol.h
	* libgimptool/gimptoolmodule.h: removed tons of warnings. Do we need
	to add -Werror to the CFLAGS to avoid such a mess in the future ?!
	Also had to enforce the GIMP coding style in lots of places :-(

	* libgimp/gimppixelrgn.c: got sick and tired of debugging plug-ins,
	so I've added checks for most parameters passed to the GimpPixelRgn
	functions. This will slow down plug-in execution a little bit but
	should help to find bugs early.
