By default, it is disabled by pref gfx.canvas.remote.recycle-used-data-surface = false. Add a capability to reuse used DataSourceSurface that was previously used for storing converted video data. Add argument gfx::DataSourceSurface* aSurface to TextureHost::GetAsSurface(). aSurface may be used as returned DataSourceSurfacefi the TextureHost supports it.
