C fast path for scaled src_x888_8888 with nearest filter
The necessity is justified by a message in the pixman mailing list:
http://lists.freedesktop.org/archives/pixman/2011-July/001330.html
NONE repeat is not supported, but could be added by tweaking
the interpretation and making use of 'fully_transparent_src'
scanline function argument.
