Add support for premultiplied alpha flag detection when creating GdkMemoryTextures. Also check if overlays have premultiplied alpha and if they do set this flag for their video info, so it will be detected when creating a GdkMemoryTexture out of them. Fixes performance issues with karaoke subtitles, as now GTK does not have to perform unnecessary multiplication.
