MrOtherGuy d64e9e129e add temporary dummy variables to support for window frame color
In 96 the old --lwt-accent-color is renamed to --lwt-frame so add some

/* Adds animated gradient border below tabs and around selected tab */
/* Might or might not work, no promises */
/* Constant animation WILL increase CPU usage */
/* Dummy variable to support versions 94-96, can be removed when 96 lands */

Thanks to /u/skenera on reddit for suggesting animating background position and using steps() function to reduce cpu load
