Glow:- Texture, added SetData method.
Merge branch 'master' of https://github.com/MarkIngramUK/glow

* 'master' of https://github.com/MarkIngramUK/glow:
  [Windows] Glow:- Make sure glew32.dll is copied to the output directory.
  Glow:- Program, added BindFragmentDataLocation
  Glow:- Removed Texture::CreateFromFile and instead created a new project GlowTex which houses this function. As creating a texture from a file isn't strictly a wrapper around existing OpenGL C API, it's better being external (compiling and linking libPng etc also becomes optional if you've already got a way of loading textures).
  Glow: File, changed path from being wchar_t to std::string. Microsoft had a non-standard extension to std::basic_ifstream which allowed a wchar_t constructor parameter.
