gimp/plug-ins/common/grid.c
Sven Neumann 28fddfd554 Makefile.am removed this header file. 
2003-03-25  Sven Neumann  <sven@gimp.org>

	* Makefile.am
	* gimpintl.h: removed this header file.

	* gimpmiscui.c: include libgimp-intl.h.

	* gimp.c (gimp_main): call setlocale() and bind to the libgimp
	textdomain so that plug-ins don't need to do that explicitely.

	* libgimp/stdplugins-intl.h: added the functionality that used to
	live in gimpintl.h and removed the libgimp related stuff. Got rid
	of the INIT_I18N_UI() macro.

	* plug-ins/*/*.c: removed all occurances of INIT_I18N_UI().
	Plug-ins simply call INIT_I18N() once in their run() function.

	* plug-ins/script-fu/script-fu-intl.h: added the functionality
	that used to live in gimpintl.h and removed the libgimp related
	stuff.

	* app/Makefile.am
	* app/gimp-intl.h: new file that defines the gettext macros for
	the GIMP core.

	* app/*/*.c: include gimp-intl.h instead of libgimp/gimpintl.h.

	* plug-ins/script-fu/scripts/test-sphere.scm: fixed typos.

/* Original plug-in coded by Tim Newsome.
*
* Changed to make use of real-life units by Sven Neumann <sven@gimp.org>.
*
* The interface code is heavily commented in the hope that it will
* help other plug-in developers to adapt their plug-ins to make use
* of the gimp_size_entry functionality.
*
* Note: There is a convenience constructor called gimp_coordinetes_new ()
* which simplifies the task of setting up a standard X,Y sizeentry.
*
* For more info and bugs see libgimp/gimpsizeentry.h and libgimp/gimpwidgets.h
*
* May 2000 tim copperfield [timecop@japan.co.jp]
* http://www.ne.jp/asahi/linux/timecop
* Added dynamic preview. Due to weird implementation of signals from all
* controls, preview will not auto-update. But this plugin isn't really
* crying for real-time updating either.
