Details:

On Debian Sid, octave 4.2.1-4+b1:


graphics_toolkit('fltk')
fplot(@(x) sin(x), [0 2*pi])
set(gcf(), 'Color', [1 0 0])
print('foo.jpg', '-djpg')


Expected result: foo.jpg contains a red background.

Actual result: foo.jpg contains a white background.

Additional information:

- In the window output the background color is correct. It's only wrong in the
resulting image file.

- This affects at least JPG, PNG, and SVG output. I have not tested others.
