When I added perpixel_op recently, I didn't get the function signature right. It only would work for plain old function pointers, and would not work properly for "functors" or lambdas with capture. I should have used function_view which can do a light-weight wrapper of all three, so now I do. Also modified imagebufalgo_test to explicitly test all three forms to be sure they work. Also update function_view ever so slightly. Signed-off-by: Larry Gritz <[email protected]>
