概要
セットアップが完了していないBakedDataをTimelineに置いたときに
Texture2D.whiteTextureをDestroyしようとしてエラーが発生していました。セットアップが完了していない場合は
Texture2D.whiteTextureではなく、new Texture2D(width, height)を返すようにしました。補足
Object.Instantiate(Texture2D.whiteTexture)を使った方法この方法で作成されるテクスチャは4x4のサイズなため、
uLipSyncClipTimelineEditor.GetOrCreateCachedTexture()でキャッシュされたテクスチャと描画したいテクスチャのサイズが常に異なり、毎回テクスチャを再生成するようになってしまうため採用しませんでした。懸念点
Textrue2Dをnewした場合はRGBAが全て205のテクスチャが作成されますが、恐らくこの仕様はドキュメントに記載されていないため明示的に白で埋めたほうがきれいかもしれません。
（今回は、あまり本質的でない処理内容が多くなってしまうため実装はしませんでした）
