yep, well except for following macros:

	__HPP_COLOR_PERCENT_FN
	__HPP_ENTRY_PERCENT_FN
	__HPP_ENTRY_RAW_FN

being so long.. any chance the main part of it being in function?

Seems like '_type' is just in function name, but the '_field' might
be the killer ;) maybe it could be 'used' in such function via PERF_HPP__*
enums instead..?

thanks,
