Georges Basile Stavracas Neto 86168b945c window-stream-source: Draw into DMA buffer image
Much like monitor streaming, implement window streaming by
making the window actor draw itself with a paint context
that used the passed framebuffer.

Now that all MetaScreenCastStreamSrc subclasses implement
blit_to_framebuffer, remove the conditional check from
meta_screen_cast_stream_src_blit_to_framebuffer().
