I send a series of patches for NEON optimizations of bilinear scaling.
It's based on latest snapshot of pixman master repository.

First patch defines a new common header macro for bilinear a8 mask scanline
In second patch, I implemented some bilinear scanline functions in a new
file pixman-arm-neon-asm-bilinear.S with modified Makefile.
Last patch just enables additional fast paths into pixman_implementation_t.

I'm sorry about the test failure in previous patch.
I used mask format symbol 'x' to indicate that there's no mask instead of
'n' which generally means 'solid mask'.

So, in this convention,


these functions are implemented in the new file.
It passes pixman scaling test now.
Any kind of review would be appreciated.

Best Regards,
Taekyun Kim
