  Support arrays of arrays in the API
  
  The ShaderVariable class that is used as an interface between the
  compiler and the rest of the code gets arrays of arrays support.
  
  Array of array variables are passed from the compiler just like any
  other variables. However, when stored in Program state each innermost
  array constitutes a separate variable. This is done to make the
  implementation match the GLES specification for program interface
  query APIs.
  
  This will be tested more fully once support for parsing arrays of
  arrays lands in the compiler.
