Xpra: Ticket #305: PNG palette indexed encoding mode

would probably save a fair amount of bandwidth. We can provide a new encoding option, maybe named "png8". This should reduce the bandwidth somewhat.

Also, let's benchmark the "optimize=1" flag to see if it is worth having, maybe as an encoding option similar to the x264 speed menu. (with just 2 options)

added support in r3446, it has to be enabled manually using:

--encoding=png/L for grayscale 8bit palette mode
--encoding=png/P for colour 8bit palette mode

It would be advantageous to use these modes automatically (at least png/P) when compressing regions with few colours... but I don't see how we could detect the presence of uniform regions cheaply enough.
