So you are saying Porter-Duff rules of the destination surface wouldn't impact the RenderTo() at all! Neither would any of the blitting flags do? Does it mean that its just a copy of the data from the image provider to the surface.

Only DSCAPS_PREMULTIPLIED can impact and nothing else?

Does RenderTo use any blit operations at the backend?

No, Porter-Duff rules and Blitting flags only affect surfaces'
drawing/blitting functions.

If the destination surface is DSCAPS_PREMULTIPLIED, the image provider
premultiplies the source during rendering.
