For use within accelerated Canvas2D, it is expedient to have a variant of Present that explicitly acknowledges that there is a copy from a supplied WebGL framebuffer into the swap chain back buffer, as is usually the case when remoting, so that it can be relied upon for format conversions or other concerns. This allows Present to remain simple and assume rendering happened directly to the back buffer, without need of a copy. This backs out some of the earlier changes to Present in 1754130 in favor of separating the new copy behavior into an explicit CopyToSwapChain interface, which supports a format swizzle that is useful for converting between Canvas2D and WebGL swap chain formats. The behavior of CopyToSwapChain, as noted, assumes that there is a supplied WebGL framebuffer that must be copied to the swap chain back buffer before any compositing should occur.
