de2afd8688 swrast: do texture sampling/combining in floating point 
The code's cleaner and a step toward supporting float-valued texture sampling.
Some optimizations for common cases can be added and re-enabled...

49fb750a68 glsl: implement compiling/linking of separate compilation units 
A shader program may consist of multiple shaders (source code units).
If we find there are unresolved functions after compiling the unit that
defines main(), we'll concatenate all the respective vertex or fragment
shaders then recompile.

This isn't foolproof but should work in most cases.

e4b27b4a69 mesa: fix a recursive display list problem 
This fixes an issue when compiling glCallList() into another display list
when the mode is GL_COMPILE_AND_EXECUTE.

Before, the call to glCallList() called _mesa_save_CallList() which called
neutral_CallList() which then called _mesa_save_CallList() again.  In the
end, the parent display list contained two calls to the child display list
instead of one.

Let's be on the lookout for regressions caused by this change for a while
before we cherry-pick this elsewhere.

28fa809c9e r300-gallium: Fix compiler warnings. 
"const" is the right keyword, but I can't do that without adding a bunch
of really annoying and ugly const casts everywhere, and frankly,
that's really stupid, so instead, just don't make them const.

919f57078b mesa: fix bug in GPU codegen for fixed-function two-sided lighting 
The 'dots' register wasn't getting properly un-negated and un-swizzled
after emitting the code for back-face lighting.  So, if more than one
light source was enabled, the specular exponent for the next light source
was wrong.

During execution we were evaluating pow(x, y) where y was negative instead
of positive.  This led to the outcome being zero or NaN.

This fixes the occasional black triangles seen in isosurf when hacked to
enable two-sided lighting.
