Image bg transparent while the ribbon's bg is black...<br>

<div class="image2" style="background-image: url(image.jpg)"></div>
<div class="current image2" style="background-image: url(image.jpg)"></div>
</div>
<hr>
Add a seporate bg tag<br>
- this effectively doubles the number of tags used for a ribbon...<br>
+ the only API that needs changing is what deals with previews and filters<br>
+ will simplify different image indicator CSS<br>
<s>+ will remove LOTS of code dealing with scaling, sizing and rotation...</s> this will not change!<br>
<div class="ribbon">
<div class="image3"><div style="background-image: url(image.jpg)"></div></div>

<!-- XXX this shows that we will still need margin-patching and resizing when rotating...

<hr>
Keep the images on one level and marks outside, after the image...<br>
+ one tag per UI element<br>
+ generic and extensible<br>
- a little bit more complicated mark manipulation during image shifting
&ndash; potential orphaned or misplaces marks...<br>
