evas_engine.c
Log Message:
1. evas gets a pipeline with deferred rendering ability (sometimes faster,
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.
