- remove all uses of builtin matrix manipulation. Only glLoadMatrix for view and projection matrix are left.

...
- make matrix class single precision.

- added some checks to the wall rendering code that will allow to disable the clip planes in many cases, even when a plane mirror portal is active. This also solves the precision issue with using world coordinates for clip checks.

- for some reason using world coordinates for clipping in the shader is somewhat imprecise so the clip plane heights have to be adjusted a bit for it.

- since the clip planes for plane mirrors did not work anymore I reimplemented them using shader based logic. It still needs to be seen if this affects performance on older hardware.

- fixed: GLPortal::DrawPortalStencil must apply the render state before drawing anything.

- use vertex buffer and reuse of data for stencil drawing. A stencil needs to be drawn multiple times with the same polygons so this is a good place to optimize.

- removed all code that mixes together the different lighting methods. Now everything goes through the 3 different light parameters in the render state.
...
- removed cm parameter from many functions.

- alternative configuration using GLEW to get extension functions. This requires GL 2.0, though so it won't be promoted to the mainline for the time being.
...
- removed all pre GL 2.0 support.

- bumped minimum supported OpenGL version to 1.4. The engine was already using several 1.3 and 1.4 features which would have caused problems on 1.2.
...
- removed gl_vid_compatibility. With the bump to 1.4 no hardware requiring this flag is supported anymore.
- disabled 16 bit framebuffers for the same reason. As a conseqence all code for rendering without stencil could also be removed.
