------- Additional Comments from Jarkko Sakkinen <jarkko.j.sakkinen at gmail.com>
Why stencil handling is done how it is done (always enable stencil when depth
is enabled). Look at http://www.opengl.org/wiki/GL_EXT_framebuffer_object:
"NEVER EVER MAKE A STENCIL buffer. All GPUs and all drivers do not support an
independent stencil buffer. If you need a stencil buffer, then you need to make
a Depth=24, Stencil=8 buffer, also called D24S8. Please search for the example
about GL_EXT_packed_depth_stencil on this page. "

For now for OpenGL ES 2.0 I've implemented only depth handling because I don't
have N900 or any other ES 2.0 device to develop and test the fixes for that
part so context attribute stencil is set to false there always.
