i prefer it not inline - at least now - why? it can change
content/functionality without needing a recompile. this is not to avoid a
function call- but a syscall (sure on x86 i know its a simple counter read) but
there is one other advantage - animations are more "synced" if they use the
same timepoint - ie the time at which select() stopped being idle (if this is
an animator then that should be pretty consistent). if you have 10 callbacks
and each gets the current timepoint to figure out where along some animation
path your are - they all refer to the same timepoint now. thats the really good
bit :) but sure - can add it to ecore_init for setup too :)
