Toshihiro Shimizu 890ddd
/*!
Toshihiro Shimizu 890ddd
  A ShaderInterface represents interface data to a GLSL shader program.
Toshihiro Shimizu 890ddd
Toshihiro Shimizu 890ddd
\par Rationale
Toshihiro Shimizu 890ddd
Toshihiro Shimizu 890ddd
  OpenGL shaders are supplied as text to be compiled at run-time by a
Toshihiro Shimizu 890ddd
  GLSL compiler. In our case, the specified text is assumed to be stored in
Toshihiro Shimizu 890ddd
  one or more files on hard-disk.
Toshihiro Shimizu 890ddd
\n\n
Toshihiro Shimizu 890ddd
  However, in order for an executable to correctly interface a GLSL
Toshihiro Shimizu 890ddd
  shader program, further interface data must be supplied in some form.
Toshihiro Shimizu 890ddd
Toshihiro Shimizu 890ddd
  Interface data include the path of the GLSL shader program file and
Toshihiro Shimizu 890ddd
  parameters to be bound by the executable before the shader is run.
Toshihiro Shimizu 890ddd
Toshihiro Shimizu 890ddd
\par Usage
Toshihiro Shimizu 890ddd
Toshihiro Shimizu 890ddd
  A ShaderInterface is loaded from an xml file. Since an interface could
Toshihiro Shimizu 890ddd
  be loaded incorrectly, remember to check the isValid() method to ensure
Toshihiro Shimizu 890ddd
  that the loading process succeeds.
Toshihiro Shimizu 890ddd
Toshihiro Shimizu 890ddd
  A loaded ShaderInterface allows access to shader parameters and
Toshihiro Shimizu 890ddd
  acts as a factory object to compiled QGLShaderProgram instances.
