2007-01-21 Michael Natterer <mitch@gimp.org> * app/tools/gimpdrawtool.[ch]: maintain an is_drawn boolean which indicates whether the drawn stuff is currently visible. Added gimp_draw_tool_is_drawn() to obtain it. * app/tools/gimpbrushtool.c (gimp_brush_tool_draw): don't create the brush outline segments for the purpose of undrawing (if we don't have the segments, we can hardly have drawn them before). Fixes artifacts when the brush is being scaled or changed. * app/core/gimpbrush.c: don't call brush_scale_mask() and brush_scale_pixmap() with zero width or height. Fixes warnings from these functions. svn path=/trunk/; revision=21749
