2005-03-09 Michael Natterer <mitch@gimp.org> More sample point stuff. Addresses bug #137776. * app/core/gimpimage-sample-points.c * app/core/gimpimage-undo-push.c: append, not prepend the sample paints to the image's list because their index matters. Update sample points when their index changes. * app/display/gimpcanvas.[ch]: added own sytles for the sample points. Added gimp_canvas_draw_text() which uses a PangoLayout which is cached in the canvas. * app/display/gimpdisplayshell-draw.c (gimp_display_shell_draw_sample_point): draw the sample points more distinct from guides using the new canvas APIs above. * app/display/gimpdisplayshell-callbacks.c (gimp_display_shell_[hv]ruler_button_press): factored out all code to (gimp_display_shell_ruler_burron_press): which takes a boolean "horizontal" variable and allows to add sample points with <control>+drag. * app/tools/gimpcolortool.[ch]: implement adding, moving and removing of sample points in the same way as the move tool moves guides. * app/tools/gimpcolorpickertool.c (gimp_color_picker_tool_oper_update): chain up.
