Previously vertex buffer did some invalid casts to references which could cause it to copy whatever was in memory into the vertex-arrays. Generally it worked up to S3DVertex - but switch from another type to S3DVertex2TCoords or S3DVertexTangents caused it to be filled with whatever was in memory behind it. Setter functions in IVertexBuffer have now overloads for all known vertex types. Also adding const version of IVertexBuffer::getData. And some warnings in comments about using the array functions (if even we mess it up...) Also de-deprecate IIndexBuffer::pointer() again. I don't like having 2 functions for same stuff, but in the end it doesn't really hurt keeping it around. git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6360 dfc29bdd-3216-0410-991c-e03cc46cb475
