I've made a couple of alterations to GUIFilmstripControl.cs to allow for control over scrollOffset through skin files. This was already implemented for list and thumb control.
I didn't know where to put the validation code to check if the supplied property through the skin file is valid. Valid should be something like no more than half the number if items on screen. So i've put it on both left and right functions.
Please let me know what you thing about this feature.
