bbd287103d mesa: prefix a bunch of #include lines with "main/". 
This is another step toward removing a whole bunch of -I flags from
the cc commands.  Still need to address driver code...

9e8a961dd7 Overhaul/simplify SWvertex and SWspan attribute handling. 
Instead of separate fog/specular/texcoord/varying code, just treat all of
them as generic attributes.  Simplifies the point/line/triangle functions.

10b5895597 Implement gl_FrontFacing for fragment shaders. 
For the time being, we put the gl_FrontFacing value in the FOGC.Y input
register.  Combining FOGC and FrontFacing in one register is a bit of a
hack and may need to be changed someday.

42c34efd23 OpenGL 2.0's two-sided stencil feature wasn't implemented correctly. 
See comment near top of stencil.c for info about OpenGL 2.0 vs.
GL_EXT_stencil_two_side.

6d460af6af Added ctx->Vertex/FragmentProgram._Enable flags. Set when vertex/fragment 
program is enabled AND the currently bound program is valid.
Check _Enable instead of Enable to prevent things from blowing up
when someone calls glEnable(GL_VERTEX_PROGRAM_ARB) without actually
defining a program.

1182ffeec3 Rename some of the tnl->Driver.* functions to tnl->Driver.Render.*, to make it 
clear that these are owned by t_vb_render.c.

Make swrast_setup opaque - it now hooks itself directly into
tnl->Driver.Render.*.  Add a _swsetup_Wakeup() call that does this.

Update X11 (tested), osmesa and FX drivers for this change.

FX compiles but is probably broken as the changes there are large.  It was the
only remaining driver that used the internal _swsetup_ functions for
interp and copy_pv.  This usage has been replaced with code from the DRI
tdfx driver.

58e9917053 Remove 'pv' parameter from Line/Tri/Point funcs. The provoking vertex 
is always the last vertex parameter.
Modify clipping to preserve pv colors.
Modify swrast and X11 driver to expect the pv in the last vertex
(was looking in the first vertex previously).
Remove all handling of flatshading from swrast_setup.

Allow drivers to override the unclipped render tabs in tnl_render_stage
directly.  (Like in 3.4).  Removed fxsimplerender stage.

Modified t_vb_rendertmp.h to remove the need for 'parity' arguments
in RENDER_TRI macros.

23caf20169 Move the transform and lighting code to two new directories 
math:  Provides basic matrix and vector functionality that
               might be useful to multiple software t&l
	       implementations, and is used by core mesa to
	       manage the Model, Project, etc matrices.

	tnl:   The real transform & lighting code from core mesa,
	       including everything from glVertex3f through vertex
	       buffer handling, transformation, clipping, lighting
	       and handoff to a driver for rasterization.

The interfaces of these can be further tightened up, but the basic
splitting up of state and code move is done.

1e1aac034c Cleanup of derived state calculation prior to seperating software T&L 
into a new directory.  Specifically the handling of changes to lighting
lighting space (light in model vs. light in eye) have been revamped.

Moved several derived values used only by swrast into that directory.

Removed direct calls to swrast_flush() from vbrender.c -- pushed into
ctx->Driver.RenderFinish.

Optimized flat-shading case in swrast_setup.

7c20642b10 A new module to provide RasterSetup and advanced triangle/line/point 
functionality layered on top of the software rasterizer.

An example entrypoint:
	void _swsetup_Triangle( GLcontext, GLuint, GLuint, GLuint, GLuint )

will coerce the software rasterizer to draw flat, twoside-lit,
unfilled and offset triangles (including decomposition to points or lines).
