//       Class : ShaderContext
// Description : The ShaderContext is meant to contain the compiled
//               version of a shader string.  ShaderContext is an
//               abstract base class, there will be a subclass of it
//               for each shader language and graphics API.
//               Since the languages are so different and the
//               graphics APIs have so little in common, the base
//               class contains almost nothing.  All the implementation
//               details are in the subclasses.
