True. On my machine (pretty old, over 6 years now) I didn't spot any
differences in working of Marble widget - the same slowness ;)

Overall with OpenGL disabled (thanks Andi!) I didn't notice major
speed up when digiKam. Maybe little faster. With testing collection
(2000 images grouped in several big folders) 0.10 feels faster than 0.9
but this collection has much smaller database in elements.
