Original commit message from CVS: * gst/smpte/barboxwipes.c: (gst_wipe_boxes_draw), (gst_wipe_triangles_clock_draw), (gst_wipe_triangles_draw): * gst/smpte/gstmask.c: (_gst_mask_register): * gst/smpte/gstmask.h: * gst/smpte/gstsmpte.c: (gst_smpte_update_mask): * gst/smpte/paint.c: (gst_smpte_paint_hbox), (draw_bresenham_line), (gst_smpte_paint_triangle_clock): constify some static structs. Don't update the mask if nothing changed to the params. Make sure we never draw outside of the picture. Fixes #398325.
