DownloadHandlerTexture crashes if it downloads invalid texture data

--

-

If a URL to non-texture data or malformed texture data is passed to DownloadHandlerTexture it will trigger a hard-crash in DownloadHandlerTexture::OnFinishReceiveData.

 

The cause appears to be that in DownloadHandlerTexture::OnFinishReceiveData CreateTextureFromBufferOnBackgroundThread can return null if the texture creation fails, one possible cause being a parsing error. The function then dereferences m_texture to call SetHideFlags.

 

The behaviour prior to the SetHideFlags call being added was that m_Texture would still end up null but this would ultimately result in a scripting exception. Since that was the case, it looks like a fix would be to simply wrap the SetHideFlags call in a null-check.
