Bug Fix

Smoothed out the size fitting algorithm, with the result of much cleaner renders.
Fixed a bug whereby if a sprite was dropped on a page with no valid position so that it went to the inventory in the position of the inventory exit, then it couldn't be picked up!

Incredible time gap...

... but I'm back at my little forge, carving this and that.
I built another test version which you can load from this handy link.
I was dissatisfied with the re-rendering engine in android java, so I built a version that only does a few sizes of playfield. It needs work, but it's viable.
