Subject: [PATCH] Attempt to build a reasonable font path for the system and
 start Xvnc with this font path.  Failing that, attempt to use the X Font
 Server (xfs.)  Note that XFS is not generally available on SuSE and Ubuntu,
 so it cannot be used as the default font path.

git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@3725 3789f03b-4d11-0410-bbf8-ca57d06f2519
