It's harmless to add support for attributes we don't support,
since they require a feature enabled for them to affect
something. As long as they aren't enabled, nothing happens.
This enables support for custom colorspaces and background colors.

The piglit draw-pixel-with-texture was asserting in the glsl->tgsi code,
due to 0 texture target, this makes sure the texture target is copied over
correctly when we copy instructions around.

This avoids the assertion, have to contemplate fixing things as per the spec

Noticed a "warning: array subscript is above array bounds" given at one of
the existing sanity-check asserts. Turns out all the arrays of strings
haven't matched the corresponding enum values in a while, if ever.
I didn't know the proper names for any of these and couldn't find
them in the base specs aside from "result.pointsize" in
ARB_vertex_program, so I just filled in the enum's value
as was done with other slots.
Also add four STATIC_ASSERT()s to be sure and catch future additions
or bumps to MAX_VARYING/etc again, and some more non-static asserts
where there weren't any before.
(Note, the fragment enum that corresponded to result.color(half) was removed in
8d475822e6e19fa79719c856a2db5b6a205db1b9.)

This helper function is used during mipmap generation to prepare space
for the destination mipmap levels.
This improves/fixes two things:
1. If the texture object was created with glTexStorage2D, calling
_mesa_TexImage2D() to allocate the new image would generate
INVALID_OPERATION since the texture is marked as immutable.
2. _mesa_TexImage2D() always frees any existing texture image memory
before allocating new memory. That's inefficient if the existing
image is the right size already.

The old interface was not useful for OpenGL and had to be reworked.
This interface was originally designed for OpenGL, but additional
changes have been made in order to make st/d3d1x support easier.
The most notable change is the stream-out info must be linked
with a vertex or geometry shader and cannot be set independently.
This is due to limitations of existing hardware (special shader
instructions must be used to write into stream-out buffers),
and it's also how OpenGL works (stream outputs must be specified
prior to linking shaders).
Other than that, each stream output buffer has a "view" into it that
internally maintains the number of bytes which have been written
into it. (one buffer can be bound in several different transform
feedback objects in OpenGL, so we must be able to have several views
around) The set_stream_output_targets function contains a parameter
saying whether new data should be appended or not.
Also, the view can optionally be used to provide the vertex
count for draw_vbo. Note that the count is supposed to be stored
in device memory and the CPU never gets to know its value.
OpenGL way | Gallium way
------------------------------------
BeginTF = set_so_targets(append_bitmask = 0)
PauseTF = set_so_targets(num_targets = 0)
ResumeTF = set_so_targets(append_bitmask = ~0)
EndTF = set_so_targets(num_targets = 0)
DrawTF = use pipe_draw_info::count_from_stream_output
v2: * removed the reset_stream_output_targets function
* added a parameter append_bitmask to set_stream_output_targets,
each bit specifies whether new data should be appended to each
buffer or not.
v3: * added PIPE_CAP_STREAM_OUTPUT_PAUSE_RESUME for ARB_tfb2,
note that the draw-auto subset is always required (for d3d10),
only the pause/resume functionality is limited if the CAP is not
advertised
v4: * update gallium/docs
v5: * compactified struct pipe_stream_output_info, updated dump/trace
It's like DrawArrays, but the count is taken from a transform feedback
object.
This removes DrawTransformFeedback from dd_function_table and adds the same
function to GLvertexformat (with the function parameters matching GL).
The vbo_draw_func callback has a new parameter
"struct gl_transform_feedback_object *tfb_vertcount".
The rest of the code just validates states and forwards the transform
feedback object into vbo_draw_func.
Xa doesn't support it yet. Trying to do that would cause a segfault.
