Renames SDCTask -> RenderPassTask and adds comments describing its
purpose. Has SDC use a DrawList and expose similar drawing functions.
Stubs out all Device methods that will eventually need to be supported,
but groups them into in-scope and out-of-scope sections. Implements the
drawing functions in terms of drawPath() and has drawPath() invoke the
SDC functions (with untested support for path effects, hairline, etc.).
