I'm dealing with a pixel test here (for bug 107848) and check-webkit-style has been complaining about auto-props on Subversion: LayoutTests/platform/mac/svg/filters/feGaussianBlur-zero-deviation-expected.png:0: Have to enable auto props in the subversion config file ($HOME/.subversion/config "enable-auto-props = yes"). Have to set the svn:mime-type in the subversion config file ($HOME/.subversion/config "*.png = svn:mime-type=image/png"). [image/png] [5]
