Transparent winterboard background to prevent winterboard from showing backgrounds but using a theme that has icons you like.
Suppose you want to use BossPaper for your backgrounds but you want to use Winterboard for icons. Your theme with icons has also a background of its own and maybe rotating wallpaper. You dont want to use the wallpaper in the theme instead you want to use bosspaper. This provides a winterboard theme that is nothing but a transparent full screen background image.
To use, move this theme to the top of winterboard and activate it. This will then be the only background that Winterboard will apply. Note, there are some widgets that incorrectly insatll using Wallpaper.html rather than Widget.html. This will disable those widgets. You should email the author of those widgets and get them updated. Wallpaper.html is intended only for wallpaper backgrounds not widgets.
