2006-06-03 Michael Natterer <mitch@gimp.org> * app/core/gimpimage.[ch]: renamed gimp_image_coords_in_active_drawable() to gimp_image_coords_in_active_pickable() and added boolean "sample_merged" and "selected_only" parameters. Use floor() instead of ROUND(), we want to round to the actual pixel, not to the nearest pixel boundary. * app/tools/gimpbucketfilltool.c * app/tools/gimpclonetool.c * app/tools/gimpcolortool.c * app/tools/gimpfliptool.c * app/tools/gimptransformtool.c: changed accordingly. Removed quite some duplicated code which checked sample_merged and the mask value at the cursor location. * app/tools/gimpbycolorselecttool.c: use the hand tool cursor, there's also a hand in the toolbox icon. Fixed cursor_update() function to set the bad modifier when there is no pickable pixel at the cursor loction. * app/tools/gimpfuzzyselecttool.c: added cursor_update() implementation which does the same as by_color_select's one. * app/tools/gimpselectiontool.c (gimp_selection_tool_cursor_update): don't override the bad modifier which was set by a subclass' cursor_update().
