The OmniView defaults to 16bpp when no SetPixelFormat is sent.
The Java applet sends SetPixelFormat (msg type 0) at
ByteColorRFBRenderer.new() line 76 to request 8bpp RGB332
(bpp=8, depth=8, true_color, red_max=7, green_max=7, blue_max=3,
shifts 0/3/6). Without this, pixel data arrives as 16bpp pairs
that produce green stripe artifacts when interpreted as 8bpp.
Verified: snapshot now matches the reference screenshot from
http://10.3.0.130/screenshot.jpg (dark screen with "Free" label).
