changed output from fps to time (in msec). Notes for dx10 and dx11: the first measure is wrong (zero), the followiing are correct; measured time includes output text to surface.

compute fps changed (now only interop counts). fixed d3d10 and d3d11 print info method (there were issues with texture mapping)

simplified sample's interface (remove odd "no processing" branch, add print to screen for processing mode)
