particular platforms.

[mtklein, 2015/10/14 18:45:17]

I'm a little skeptical about some of these additions, but I'm willing to start
wide and pull back.  I don't think we use anything in include or src related to
animator, nacl, svg, views, or xml.

[dogben, 2015/10/14 23:11:05]

svg is used in dm/DMSrcSink.cpp, and xml is used by svg.

src/effects/SkMorphologyImageFilter.cpp uses src/effects.

I moved src/codec to DM_INCLUDES.

same with DM_DEPS.
