2000-06-09 Michael Natterer <mitch@gimp.org> Cursor patch II: This is only the logic inside the cursor system and not yet used. * app/cursorutil.[ch]: [gimp]_change_win_cursor() take lots of parameters now and compose cursors from up to three cursor bitmaps/masks. * app/gdisplay.[ch]: As a test, create a hardcoded example cursor if "Cursor Mode" is set to "Tool Icon with Crosshair" in prefs. * app/curves.c * app/dialog_handler.c * app/scroll.c: changed the calls to the win_cursor function. * app/tools.[ch]: added a cursor and a toggle cursor to the ToolInfo structure of all tools. * app/toolsF.h: new ToolType TOOL_TYPE_NONE. * app/gimpdnd.c * app/interface.c: check for silly filenames in the file dnd callback. Closes #13733. * Makefile.am * cursors/bucket_fill_small.xbm * cursors/bucket_fill_small_mask.xbm * cursors/crop_small.xbm * cursors/crop_small_mask.xbm * cursors/crosshair_small.xbm * cursors/crosshair_small_mask.xbm * cursors/ellipse_select_small.xbm * cursors/ellipse_select_small_mask.xbm * cursors/eraser_small.xbm * cursors/eraser_small_mask.xbm * cursors/free_select_small.xbm * cursors/free_select_small_mask.xbm * cursors/fuzzy_select_small.xbm * cursors/fuzzy_select_small_mask.xbm * cursors/intersect.xbm * cursors/intersect_mask.xbm * cursors/minus.xbm * cursors/minus_mask.xbm * cursors/move.xbm * cursors/move_mask.xbm * cursors/paintbrush_small.xbm * cursors/paintbrush_small_mask.xbm * cursors/pencil_small.xbm * cursors/pencil_small_mask.xbm * cursors/plus.xbm * cursors/plus_mask.xbm * cursors/rect_select_small.xbm * cursors/rect_select_small_mask.xbm * cursors/resize_small.xbm * cursors/resize_small_mask.xbm * cursors/zoom.xbm * cursors/zoom_mask.xbm * cursors/zoom_small.xbm * cursors/zoom_small_mask.xbm: new files extracted from Tigert's gimp-tool-cursors.xcf created at GimpCon. Tigert, I'll commit the xcf as soon as I've added empty layers with the names of the cursors that are missing. * cursors/mouse.xbm * cursors/mouse_mask.xbm: made it 32x32 to allow for cursor composition.
