Hardwire function call instead of using callbacks. We don't actually need

callbacks, it was done for making 2 functions static, not to pollute the
global functions space but that had its price of 8 bytes overheat per
allocation, which is just too much. Also making the app member 32b instead
of 64b, which should save additional 4 byte, to the total of 12 byte per
allocation of a row buffer.
