AddDynamicTextureURL()
RenderPlugins[contentType].AsyncConvertUrl(updater.UpdaterID, url, extraParams);
   contentType を持つモジュールの AsyncConvertUrl() を呼び出す．

RenderTerrainScale

• void LLDrawPoolTerrain::renderFullShader() の sDetailScale
• デフォルトは 7, テクスチャは （リージョンサイズ/7） 個繰り返し表示される．1/7 = 0.14285714
• UVMap は (リージョンサイズ/7) 倍される．
• 256にすれば，1枚の画像．
