No. Not really. No one tried before. So you are a real pioneer ;)

Mh, not really. You can only pass one exact color value ... which is
braindead when using video. Press ctrl-v in the console to set a blit
value (mh, yes, that is buggy) or via javascript set_blit_value().
For images it is better to use an alpha channel and srcalpha blit.

Yes, the search path needs more documentation. Freej will look in
~/.freej/plugins/ so you can do

cd ~
mkdir -p .freej/plugins
cd .freej/plugins
ln -s /usr/local/path/to/frei0rs/*.so .

start freej with -d3 to get some more debug output and -c to disable
console so you don't miss any messages.

The seek() function is currently disabled. The MovieLayer will be reworked.
