Fix inconsistent marker size between screen and printout (bug #57552) * gl2ps-print.cc (gl2ps_renderer::init_marker): undo changes from cset 46fe22bf1458. * gl-render.h, gl-render.cc (m_printing): New bool data member. (opengl_renderer::draw_figure): Initialize m_printing with the depending on "__printing__" property. (opengl_renderer::points_to_pixels): New method to convert points data to pixels. Returns the original value when renderering for printing purpose. (opengl_renderer::set_linewidth, opengl_renderer::set_linewidth, opengl_renderer::make_marker_list): Use points_to_pixels. * print.m: Comment out line which prevents redrawing plot after printing. The markersize may have been changed for printing and this requires a redraw.
