[gst-devel] top-down vs bottom-up DIBs

[Julien Isorce]

Ok.  Bottom-up is something weird and it seems to come from MS windows. But
a mutli-platform framework required some modularity (do not know if it is
the exact word !). That's the big point isn't !

Specify the direction in the caps, as you said, could be a first step.

Thx a lot.
