software-16 uses. it works and in some cases gets massive speedups (70%+) but
in a few its slowdowns (30% down) in expedite tests - why, i don't know. it
should be the same or better in all tests. disabled for now - also not
complete. < 32bpp wont' work and not sure rotation works and masks don't work
either.

sometimes slower)
2. --enable-pthreads will enable multi-threaded rendering (current support is
for up to 4 threads so if you have a new fanled quad core or dual cpu dual
core box or whatever you will in theory be able to max moe of its cpu grunt
with the software rendering engine. this can only be done because i added the
pipelines which means almsot entirely lock-free multithreading internally in
evas. the only locks are for fonts but with a little work i might be able to
remove some/most of those too)
for now pthreaded rendering likely will be linux only (it relies on sched.h
for setting scheduler params to force the slave threads to run on separate
cpu's as linux likes to keep them on the same cpu otherwise and thus we get
no speedups at all - only slowdowns).
aso note that it is a bit of a mixed bag. complex ops (like smooth scaling
with alpha blending) get speedups, but simple ops (like blits/fills) slow down.
this all neds examination and tweaking still - but it's a start.

debugging/fixing and likely int he end the exact same result of fixing them.
yes - we lose performance - but it actually is correct now :) if we want to
do such radical changes- i sugegst moving to premultiplied alpha and makign a
tonne of externally tested routines in a test harness first to compare
correctness and speed in an isolated environment.

do NOT depend on order operation precedence. it broke scaling. laos other
completely bizarre mmx things were going wrong with mm7 ending up not 0 so
i've had to force it to be 0.

with texture upload. it does NOt check error returns anywhere from gl... this
may mean issues with LOTs of images, LARGE images etc. need to fix that later

unreachable code paths until the corresponding functions are complete and
committed.
