Previously 3D textures were mipmapped using multiple passed through
the 2D mipmap generation code. This had 3 disadvantages. First, the
extra passes were slow. Second, this required the allocation of a
temporary buffer to hold intermediate data. Third, and most
important, the extra passes caused loss of additional bits due to
integer division / bit-shifting.
With this change, our mipmapgen conformance test passes for
non-compressed texture formats.

Note how if:
x + width == xmax + 0: width -= 0
x + width == xmax + 1: width -= 0
x + width == xmax + 2: width -= 1
So, the function was clipping to [xmin, xmax+1), not [xmin, xmax) like it was
supposed to. Same for ymax.

The subsequent if/else cases always call _mesa_reference_fragprog() anyway.

get_fp_input_mask()
This is a work-around the for the fact that we do fragment shader state
validation before vertex shader validation (see comments in state.c) so in
get_fp_input_mask() we can't rely on ctx->VertexProgram._Current being up to
date yet.
This fixes a glean glsl1 test failure.

The problem we're solving only occured when there was a user-defined
vertex shader but no fragment shader. Check for that case now.
Fixes glean api2 vertex array failure.

This reverts commit 8dc88cb64305c591dfadded2b5acbb1e6b04cd7f.
This change broke other things...
|
|
We were accidentally using the fixed-function logic when a vertex shader was
being used.

It is possible for applications to specify any texture base level,
including trivially invalid values (i.e., 47000000). When an app
specifies an invalide base level, we should gracefully disable the
texture instead of accessing memory outside the gl_texture_object.
This fixes an occasional segfault in one of our conformance tests.

add some more srgb texture formats, including compressed ones
various fixes relating to srgb formats
issues: _mesa_get_teximage is completely broken for srgb textures,
both for non-compressed ones (swizzling) and compressed ones
(shouldn't do standard-to-linear conversion)
texelFetch function may be broken for little or big endian
(or both...)

The ctx->Driver.GenerateMipmap() hook only expects cubemap face enums, not
CUBE_MAP_ARB, so walk all faces when we encounter that. Fixes oglconform
fbo.c segfault with both swrast and i965 drivers.

These arrays will indicate per-input or per-output options for vertex/fragment
programs such as centroid-sampling and invariance.

texture comparison logic is bypassed if the currently bound texture is not
a depth/depth_stencil texture.

This fixes glReadPixels(GL_LUMINANCE, GL_FLOAT)/glGetTexImage(GL_LUMINANCE, GL_FLOAT) issue
on fixed-point color buffers.

Dots is re-used if more than one light is enabled. Previously
the negate flag of dots may affect next light.

This fixes a lighting issue when drawing a bitmap.

than the python generators
Specifically:
#include "glapitable.h" in src/mesa/main/glapi/dispatch.h
Call _mesa_bsearch() in src/mesa/main/enums.c.

See bug 18445.
When getting array results, __glXReadReply() always reads a multiple of
four bytes. This can cause writing to invalid memory when 'n' is not a
multiple of four.
Special-case the glAreTexturesResident() functions now.
To fix the bug, we use a temporary buffer that's a multiple of four bytes
in length.
NOTE: this commit also reverts part of commit 919ec22ecf72aa163e1b97d8c7381002131ed32c
(glx/x11: Added some #ifdef GLX_DIRECT_RENDERING protection) which
directly edited the indirect.c file rather than the python generator!
I'm not repairing that issue at this time.
