Require DirectFB version 0.9.15 instead of 0.9.13. This simplifies the build system at the cost of requiring a library version that was released at the end rather than the middle of 2002. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@32251 b3059339-0415-0410-9bf9-f77b7e298cf2 Simplify DirectFB check. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@32252 b3059339-0415-0410-9bf9-f77b7e298cf2 Require DirectFB version 0.9.22. This allows getting rid of a lot of library version check #ifdeffery. Release 0.9.22 is from February 2005, so the requirement is reasonable. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@32253 b3059339-0415-0410-9bf9-f77b7e298cf2
