Changed var_export() calls to use "true" as second parameter. Not sure which PHP version it was added in, but I could have sworn it wasn't there last time I checked.
input.radio {border:1px none #000; background:transparent; vertical-align:middle;}
.panel_wrapper div.current {height:80px;}
#width {width:50px; vertical-align:middle;}
#width2 {width:50px; vertical-align:middle;}
#size {width:100px;}
