1e5772f0ba Don't let FragmentProgram._Active influence choice of vertex vs pixel 
fog.

ac6728d2d9 Previously in TXP and TEX instructions, lambda was passed to 
fetch_texel as zero, but I believe this is incorrect.  The spec uses a
pseudocode function:

      vec4 TextureSample(float s, float t, float r, float lodBias,
                         int texImageUnit, enum texTarget);

to specify the behaviour of TEX, TXB and TXP instructions.  For TEX
and TXP, lodBias is passed as zero, TXB is passed with texcoord[4].  In our code we have

      static void
      fetch_texel( GLcontext *ctx, const GLfloat texcoord[4], GLfloat lambda,
                   GLuint unit, GLfloat color[4] )

and were passing zero and a biased lambda value respectively.  The
difference is that TextureSample() would add in the lambda term
itself, while in our code the caller is expected to do this.  Thus in
the TEX and TXP cases, it is necessary to pass an unbiased lambda
value for things to work out correctly.

363d0bcf01 Test for texcoord[3] == zero before dividing. Not so sure about this 
test - if texcoord[3] is zero, we'd probably be fine except for an
ASSERT in IROUND_POS() which gets triggered by the inf values
created.

3509fd8c1b Rename temp_flag to temp_in_use. Use ctx->Const.MaxVertexProgramTemps 
rather than MAX_NV_VERTEX_PROGRAM_TEMPS and deal with this possibly
being greater than 32.

6258b76c49 Port Mesa to build on a P64 platform (e.g., Win64). P64 platforms 
use 64-bit pointers and 32-bit longs.  So, operations like casting pointers
to unsigned long and back to pointer won't work.  glheader.h now
includes files to define uintptr_t, which should instead be used for
this sort of operation.  It is an integer type that is the same size
as a pointer.
