Well, that's not right. If the H2200 doesn't have a FP coprocessor,
integer pixops should be faster. I was going to ask if you passed the
parameter "--enable-integer-pixops" to the script configure (or
autogen.sh), but I'm supposing you did since there was obviously a
difference (the code would almost be identical to stock if integer-ops
wasn't enabled. I, ah, might have made some changes).

Thanks for the test program. I'm working to improve it to add some more
metrics. Will post when ready. (We really should have some kind of code
versioning system going on.)
