The newest `master` branch should fix the interaction between image
alpha channel and "transmit all" (and "filter all" likewise), AND also
implement auto-detection of TIFF alpha mode.

As I'm not really sure whether some existing scenes might be relying on
the old quirk, the new "transmit/filter all" behaviour requires
"#version 3.71".

I'll publish one of those famous(?) semi-official builds once I've
gotten me a fresh batch of round tuits (presumably next weekend).
