I optimized the NEON and Generic paths for ManagedSurface::blendBlitFrom
and the new TransparentSurface::blit. Now (on arm), the new blit function
matches the speed of the old blit function even with the added
inderections that the runtime extension detection code adds in.
Other than that, I made a benchmark for this code and you can make it
using this command:
CFLAGS="-DTEST_BLEND_SPEED" make test
I reverted wii to not use altivec anymore since it doesn't.
I also removed graphics/blit-neon.cpp from graphics/module.mk because
simply including the .cpp file in graphics/blit-alpha.cpp was a better
option because then I didn't need to instantiate every version of the
templates that I needed.
Different platforms have different levels of support of encodings and
often have slight variations. We already have tables for most encoding
with only CJK missing. Full transcoding inclusion allows us to get reliable
encoding results independently of platform. The biggest con is the need for
external tables encoding.dat.
It removes a duplicate table for korean in graphics/korfont.cpp
