Consider the color space as an hypercone with apex alpha=0
and base alpha=1 instead of an hypercube.
Make the encoder consider very transparent colors more similar
even if the hue is very different.
This corresponds roughly to using the alpha as a weight for the
color difference.
Only 4 bits of alpha are used, because this is what dvdsub uses,
and it avoids overflows.

Fix trac ticket #2005.

Use the first 64 bits of the SHA1 of the content as file UID
instead of a random number if the bitexact flag is set.

Limelight is a not too uncommon CDN. The authentication scheme is
pretty similar to the adobe authentication, but is even closer to
normal http digest authentication (but not close enough to warrant
sharing code) than the adobe version.

This is mostly used to authenticate the client when publishing.
Tested with wowza and akamai.

Some but not all servers support resending a new connect invoke
within the same connection, so always reconnect for sending a new
connection attempt. This matches what other applications do as well.

The authentication scheme is structurally pretty similar to http
digest authentication, but uses base64 instead of hex strings.
