updated to new version of AMS; not tested
more changes to get it more working with uams
little cleanup, no java support
fixed afterimage -draw_save for X support to use new asvisual for each image rather than reusing one which may be from the wrong drawx->disp previously
added -x_virtual support to start and use Xvfb instead of regular X server (note that colormap is no working correctly it seems)
run Xvfb with a depth of 24 (32 doesn't work for me), the default 8 produced an incorrect color map
add -draw_save_single_file to recycle same file for saved images
Merge branch 'barry/x-virtual' into barry/uams
need to start AMS server after Xvfb or else Xvfb cannot load keyboading mapping, no idea why.
completed allowing generating graphics with Xvfb, works with AMS
updates to AMS interface include simple bash scripts
converted uAMS usage to SAWs usage; starts server but cannot see any published directories
updated to work with most recent SAWs
fixed getStack.bash for new SAWs
update for latest SAWs
updated PETSc to use a hierarchy of SAWs directories, doesn't work properly
updated to new /dir1/dir2/variablename scheme for SAWs
added support for -saws_log
updated to latest SAWs API
locking object cannot involve locking stack or code hangs on the second lock
missspelling and wrong use of CHKERRQ
