To protect the world from the soft float library...
To unite all arithmetic within our binary...
To denounce the evils of floating point precision...
To save more kilobytes - that's our vision....
(god this is cringe)
All floating point math has been eliminated, and replaced with
equivalent or near-equivalent fixed-point math.
sprite_data.cpp uses Q16, and get_rand_range uses a full Q32 to
ensure that the exact same results are generated as before, at
the cost of some inline assembly to do a umull (__aeabi_lmul is a
little excessive when the lower 32 bits are discarded)
This eliminates all of the expensive double precision float library,
saving a few kilobytes.
Additionally, the unneccessary parts of nanoprintf have been
disabled. There is no need for precision specifiers, long longs, or
floats.
