Make graphic functions visually compatible w/Matlab. * image.m: Turn "box" on. * legend.m: Use '#' in BIST titles. * area.m: Turn "box" on. Fix transpose operator that was accidentally changed to `"'. * colorbar.m: Turn "box" on. Remove logscale colorbar BIST demo since it doesn't work for Octave or Matlab. * contour.m: Turn "box" on. * fill.m: Turn "box" on. * isosurface.m: Use cell array of strings in annotation box of %!demo to get multi-line strings. Remove newline. * light.m: Use cell array of strings in annotation box of %!demo to get multi-line strings. * loglog.m: Turn "box" on. * loglogerr.m: Turn "box" on. * __bar__.m: Turn "box" on. * __quiver__.m: Rename 'h' to 'hax' for clarity. * quiver.m: Turn "box" on. * semilogx.m: Turn "box" on. * semilogy.m: Turn "box" on. * shrinkfaces.m: Call 'axis auto' to update plot limits before calling 'axis equal'. This is a kludge that should be fixed in axis. * stairs.m: Turn "box" on.
