Loading splash issue

A line is missing in the CSS for the loading screen. If the user is using a border radius the white background’s corner will flood over the radius.

The last line is my fix, though in reality it should be the radius that the user supplied, minus 2px. My radius is 10px, so I am using 8px here.

.easingsliderlite-preload {
    background: url(../images/loading.gif) no-repeat center center #fff !important;
    width: 100% !important;
    height: 100% !important;
    position: absolute !important;
    top: 0 !important;
    left: 0 !important;
    z-index: 50 !important;
    border-radius: 8px !important;
}
