thumbnailBox: Stop using Shell.GenericContainer

Browse Source 
This is another straight port from Shell.GenericContainer.
The important thing to notice is that the calculation is
broken if the StThemeNode helpers (adjust_preferred_* and
adjust_for_*) aren't used.

The downside of this patch is that it removed the skip_paint
from the thumbnails. Keeping it would add an unecessarily
large amount of code.
