please test ftview

[Alexei Podtelezhnikov]

Hi all,

I have made some changes to how ftview selects the color depth mode so
that there are fewer conversions of the image data. As a result, the
32-bit mode is much more readily used. I would appreciate it if you
test it especially if you have some rare hardware or x11 forwarding
with mismatched endianness. How do these modes look?

$ ftview -d 800x600 40 font.ttf
$ ftview -d 800x600x24 40 font.ttf
$ ftview -d 800x600x32 40 font.ttf

Thank you,
Alexei
