to GL_SHORT/GL_BYTE".
This commit "mesa: fix packing of float texels to GL_SHORT/GL_BYTE" replaced *_TO_BYTE to *_TO_BYTE_TEX because *_TO_FLOAT_TEX are used to unpack the texels to floats.
In this case *_TO_FLOATZ in function extract_float_rgba also should be replaced to *_TO_FLOAT_TEX. Underline that these macros automatically preserve zero when converting.
The regression was observed on 3 oglconform tests:
snorm-textures basic.getTexImage
snorm-textures advanced.mipmap.manual.getTex
snorm-textures advanced.mipmap.upload.getTex

As far as I can tell, the Intel mesa driver is the only driver in the world
still supporting this legacy extension. If someone wants to do bump
mapping, they can use shaders.

Previously, we would unpack the texels to floats using *_TO_FLOAT_TEX,
and then pack them into the desired format using FLOAT_TO_*. Unfortunately,
this isn't quite the inverse operation, and so some texel values would
end up off-by-one.
This fixes the GL_RGB8_SNORM and GL_RGB16_SNORM subcases in piglit's
arb_texture_view-format-consistency-get test on i965. The similar 1-, 2-
and 4-component cases already worked because they took the memcpy path
rather than repacking.

When performing a ReadPixels operation, we may be reading from a buffer that
stores alpha values, but that is actually representing a buffer with no alpha
channel. In this case, while rebasing the values, touch up all alpha values
read to 1.0.
This commit fixes the following piglit (sub) tests:
ARB_texture_float/fbo-colormask-formats
GL_RBG16F_ARB
EXT_texture_snorm/fbo-colormask-formats
GL_RGB16_SNORM
GL_RGB8_SNORM
GL_RGB_SNORM
It likely improves the results of other tests as well, but a PASS remains
elusive due to additional bugs.

Rename _mesa_pack_rgba_span_int to _mesa_pack_rgba_span_from_uints.
Add _mesa_pack_rgba_span_from_ints.

The final step of _mesa_unpack_depth_span is to take the temporary
GLfloat depth values and convert them to the desired format. When
converting to GL_UNSIGNED_INTEGER with depthMax > 0xffffff, we use
double-precision math to avoid overflow and precision problems.
Or at least that's the idea. Unfortunately
GLdouble z = depthValues[i] * (GLfloat) depthMax;
actually causes single-precision multiplication, since both operands are
GLfloats. Casting depthMax to GLdouble causes the scaling to be done
with double-precision math.
Fixes a regression in oglconform's depth-stencil basic.read.ds test
since c60ac7b17993d28af65b04f9bbbf3ee74c35358c, where the expected and
actual values differed slightly. For example, 0xcfa7a6 vs. 0xcfa7a4.

Use it where performance matters more and the exact method of float->int
conversion/rounding isn't terribly important. There should no net change

In the core, we always treat spans of int/uint data as uint, so this
extract function was truncating storage of integer pixel data to a n
int texture to (0, max_int) instead of (min_int, max_int). There is
probably missing code for handling truncation on conversion between
pixel formats, still, but this does improve things.

This just adds the correct checks and asserts in the right places. This doesn't
fix all the tests that I've sent to piglit, need to add int paths to go alongside the uint paths that don't go via float to fix it up properly.
