	* app/gimage_mask.[ch]: made function headers ansi compliant.

	* app/file_new_dialog.c
	* app/preferences_dialog.c: minor GUI and signal handling
	changes. Added a WM hint pixmap to the prefs dialog but commented
	it out because it looked ugly. If someone has a nice pixmap,
	please try it and tell me ;)

	* app/color_picker.c
	* app/crop.c
	* app/info_window.c
	* app/perspective_tool.c
	* app/rotate_tool.c
	* app/scale_tool.c
	* app/info_dialog.[ch]: the info_dialog allows scales, spinbuttons
	and sizeentries now. Made some dialogs use these widgets and
	added unit support. Sprinkled some g_snprintf's, removed
	#include's, ansi issues, ...

	* app/session.c: don't call a NULL callback.

	* libgimp/gimpsizeentry.[ch]: new function
	gimp_size_entry_add_field() which allows a more flexible GUI
	layout. More intelligent signal handling.
