[Libvisual-devel] overlay, param, after 0.1.6

[Dennis S. <sy...@yo...>]

The new overlay function is almost finished, it will look for an alpha
channel when the source is a 32 bits surface and it's capable of
blitting to every depth. It also supports placement offsets. It's not
that special, but it's nice to know that when the webcam plugin lands
it'll enable us to walk in front of visuals. That with alpha chroma
keying enabled (blue screen stuff) rocks :).

I've did some quick thinking about the param stuff, and the UI it will
later include. I came to the following.

The VisParam stuff can be of a few types, ints, strings, 'color', 
filepath.. such things. Ranges can be defined etc.

When we start working on the UI support I think it's good to make
another system VisUIHints and VisUI. VisUIHints includes descriptions
about a user interface  to which params can be linked. VisUI is an
inbuffer UI creator for these hints. But let's start with VisUIHints
and a Gtk config created from this... Btw this is not yet close to
be done :), just ideas and planning...


After 0.1.6 I would like to do an 'extensive' robustness audit, API
audit... I'm starting about this right now so that when you spot
issues that need attention you can write them down and we can
create a list after 0.1.6 and fix them.

Cheers,
Dennis
