try to make available all slide images using threads
Graphic::makeAvailable() is not thread-safe, but the jpeg loader
is capable of that, and the graphic can be loaded using the stream
data (which is what ultimately makeAvailable() will do anyway).
This loads all images faster using threads instead of them being
loaded one by one on-demand.
