Function resolve_msaa

pub fn resolve_msaa(surface: &mut RCHandle<SkSurface>)

If a surface is a Ganesh-backed surface, is being drawn with MSAA, and there is a resolve texture, this call will insert a resolve command into the stream of gpu commands. In order for the resolve to actually have an effect, the work still needs to be flushed and submitted to the GPU after recording the resolve command. If a resolve is not supported or the Surface has no dirty work to resolve, then this call is a no-op.

This call is most useful when the Surface is created by wrapping a single sampled gpu texture, but asking Skia to render with MSAA. If the client wants to use the wrapped texture outside of Skia, the only way to trigger a resolve is either to call this command or use gpu::DirectContext::flush.
