Support tinting in GtkCellRendererPixbuf (#162903, Jorn Baayen):

Browse Source 
2005-01-20  Matthias Clasen  <mclasen@redhat.com>

	Support tinting in GtkCellRendererPixbuf (#162903, Jorn Baayen):

	* gtk/gtkcellrendererpixbuf.c (gtk_cell_renderer_pixbuf_class_init)
	Add a follow-state property which when TRUE causes the pixbuf
	to be tinted according to state.

	* gtk/gtkcellrendererpixbuf.c (gtk_cell_renderer_pixbuf_render):
	Use follow-state and colorize the pixbuf when appropriate.
