asarium 8c88b68327 Use OpenGL vertex array objects for better performance ...

The original OpenGL Core changes only used a single vertex array object
for specifying the data layout of our vertex data. This uses the OpenGL
extension GL_ARB_vertex_attrib_binding to extend that so that each
vertex_layout uses a separate vertex array object which should improve
performance by reducing the CPU overhead while switching the vertex
layout. Since we need to use offsets into the vertex buffers at some
points this can not be done with the core functions since those do not
support specifying an offset when binding a vertex buffer.
GL_ARB_vertex_attrib_binding does support that and also features an
improved API for specifying the vertex layout. If that extension is not
available then the rendering engine will fall back to the current code.

In CPU intensive scenes I observed a frametime improvement of 1-2 ms.

3d.h

Remove graphics functions for explicit clipping planes

3dclipper.cpp

Cleaned up more rendering code. Shrunk the vertex struct since we don't use spec_rgb anymore. Removed any declarations using the old geometry batcher. Streamlined desaturation in the model shader to use the main color uniform. Removed old unneeded interp_ code. Removed stored geometry shader parameters from the shader constants since we're no longer using the EXT version of geometry shaders.
