basic implementation of issue #2
by feel, best performance, changed immediateRender to true, springStiffness to 7 - issue #2
cant set blendTime to 0, causes strange behavior in navigator and lip tile sources. should have made the basic config changes in #2 and #3 in a diferent branch related to #4. will do before pulling
reverting a couple changes to core openseadragon options unrelated to issue #2 . will explore these in #4 were they have already been referenced.
blendTime needs to be equal to animationTime to avoid blurred images
