  Refer to GLSL extensions through TExtension enum
  
  Extensions are now referred to by enum values instead of strings most
  of the time. This gets rid of unnecessary copying of strings. The code
  is easier to work with than before as typoing the extension enum names
  will be caught by the compiler.
