2003-05-02 Pedro Gimeno <pggimeno@wanadoo.es> * app/paint/gimppaintcore-stroke.c (gimp_paint_core_stroke, gimp_paint_core_stroke_vectors): Save brush pointer before first stroke and restore it after. Fixes bug #102162. * plug-ins/common/flarefx.c (FlareFX): Use gimp_fixme_preview_do_row instead of memcpy. Fixes bug #112042 for this plug-in. * plug-ins/common/jigsaw.c: Several cleanups. (jigsaw_values_changed): New function as a result of the cleanups. (jigsaw): Use gimp_fixme_preview_do_row instead of memcpy. Together with the fix to flarefx, fixes bug #112042. (draw_jigsaw): Warn if passed a NULL buffer (solves the crash reported in bug #112012). * plug-ins/gimpressionist/orientation.c: Slightly reformatted. (create_orientationpage): Modify orientfirst/orientlast instead of sizefirst/sizelast in the corresponding adjustments. Fixes bug #112061.
