* configure.ac : added --enable-goom and --with-goom-tree. Btw, I use a

special goom tree source as I was unable to use standard goom library.
(I will provide it once mmx/ppc included)
 * modules/visualization/Modules.am: added goom
 * include/vlc_block.h src/misc/block.c: introduce a new data block
 api (not yet tested, ported from my local new input work).
