mfeemster 19cb27b83a --User changes 
-Remove some warnings about interpolation type on first and last flames.

--Code changes
 -Make DE block size always be 16x16, this should help stability on some Nvidia cards. No changes for AMD cards since they were that size already.
-Since the block size is now so small, do not reduce it further when supersampling.
 -Clean up some variable names and documentation around OpenCL DE to be more clear.
