This may help with the SQ3 scaling/line drawing problem:
Purify reports an array bounds write when simply pressing the spacebar to
evoke the text input window:
gfx_draw_line_buffer_1 [gfx_line.c:89]
gfx_draw_line_pixmap_i [gfx_support.c:98]
sdl_draw_line [sdl_driver.c:497]
gfxop_draw_line_clipped [operations.c:996]
gfxop_draw_rectangle [operations.c:1083]
gfxwop_rect_draw [widgets.c:589]
gfxwop_container_draw_contents [widgets.c:1397]
gfxwop_list_draw [widgets.c:1607]
gfxwop_port_draw [widgets.c:1986]
