* - grabber auto off when not set as active prio - join aml and fb - on aml platform both grabbers are needed, so they joind in one module and share one prio. user don't the the nasty magic behind - aml: preparation for direct ge2d access * just save it, in the middle of ge2d impl * fix compile issues * now grabbing works basicly * add 3d support for ge2d * next step, we got some video from aml * switch back to rgba * remove unfinished ge2d stuff * commit missing changes * some urgent fixes, needs some beautifying, but it works now * fixes and refctoring
