feature request: show rating as overlay in fullscreen mode

using fastrawviewer for culling of large sets of wedding photos, it would be very helpful to have the option of displaying the star rating as an overlay in fullscreen mode. ideally in an rather unobtrusive way, so in the lower part of the image, with transparent background, as to not obscure the composition of the image. 

of course i can show the menues or the bottom bar with a keyboard shortcut, but then the displayed size of the image jumps. and the general impression of the composition of the image is a little biased by the bar/menue. it maybe doesn't seem like much, but when culling thousands of images quickly, every small bit of distraction do take their toll. 

big thanks, and all the best!
