67		\section1 Using OpenGL ES rendering commands
68
69		To update the scene, we reimplment QGLWidget::paintGL(). We use OpenGL ES
70		rendering commands just like we do with standard OpenGL. Since the OpenGL
71		ES common light profile only supports fixed point functions, we need to
72		abstract it somehow. Hence, we define an abstraction layer in
73		\c{cl_helper.h}.

76
77		Instead of \c glFogxv() or \c glFogfv() we use \c q_glFogv() and to
78		convert the coordinates of a vertice we use the macro \c f2vt(). That way,
79		if QT_OPENGL_ES_CL is defined we use the fixed point functions and every
80		float is converted to fixed point.
81
82		If QT_OPENGL_ES_CL is not defined we use the floating point functions.

85
86		This way we support OpenGL ES Common and Common Light with the same code
87		and abstract the fact that we use either the floating point functions or
88		otherwise the fixed point functions.
