Retrieve native ('hardware') pointer to a texture.
Use this function to retrieve a pointer/handle corresponding to a particular texture
as it is represented on the native graphics device level.
This can be used to enable texture manipulation from native code plugins.
On Direct3D-like devices this returns a pointer to the base texture type (IDirect3DBaseTexture9
on D3D9, ID3D11Resource on D3D11). On OpenGL-like devices the texture "name" is returned;
cast the pointer to integer type to get it. On platforms that do not support native code plugins,
this function always returns NULL.
Note that calling this function when using multi-threaded rendering will synchronize with the rendering
thread (a slow operation), so best practice is to set up needed texture pointers only at initialization
time.
