--Bug fixes

-Nvidia OpenCL compilation was broken for density filtering due to ambiguity in the arguments to min(). Fix it by casting.
 -Put Nvidia block size in DE back to 24 where it used to be. Nvidia fails when it's 32.
 -Fix misspelling of the word "Rendering" in failure messages in final render dialog.
 -Put FillSummary() back when loading an ember.
 -Properly disable add final xform button when a final xform is present.
