Returns now getMipMapsData instead which for now will always be 0 in this case (but might work one day) Also removing comment about ITexture::lock() mipmapLevel parameter being broken. It got fixed in November 2019. git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6563 dfc29bdd-3216-0410-991c-e03cc46cb475
