commit: http://git.buildroot.net/buildroot/commit/?id=d4a54ed5157472f8e3c72f58bd79ab014845f03f
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

TightPNG encoding speeds up HTML5 based VNC clients like noVNC.
libvncserver enables this encoding if both libpng and jpeg libraries
are available.

[Thomas: rewrap Config.in help text.]
