Pixel count can be negative (this could be fixed elsewhere), so adapt the
functions to work with such inputs correctly (same behaviour as non-optimized
functions).
Bugzilla #2317

src/mesa/glapi. Basically, the scripts that did simple things (like
gl_offsets.py) were simple, and the scripts that did more complicated things
(like glX_proto_send.py) were getting progressively more and more out of
control. So, I re-write the foundation classes on which everything is based.
One problem with the existing code is that the division between the GL API
database representation and the way the output code is generated was either
blury or nonexistant. The new code somewhat follows the
Model-View-Controller pattern, minus the Controller. There is a distinct
set of classes that model the API data, and there is a distinct set of
classes that generate code from that data.
One big change is in the class that represents GL functions (was glFunction,
is now gl_function). There used to be an instance of this calls for each
function and for each alias to that function. For example, there was an
instance for PointParameterivSGIS, PointParameterivEXT, PointParameterivARB,
and PointParameteriv. In the new code, there is one instance. Each
instance has a list of entrypoint names for the function. In the next
revision, this will allow a couple useful things. The script will be able
to verify that the parameters, return type, and GLX protocol for a function
and all it's aliases match.
It will also allow aliases to be represented in the XML more compactly.
Instead of repeating all the information, an alias can be listed as:
<function name="PointParameterivARB" alias="PointParameterivEXT"/>
Because the data representation was changed, the order that the alias
functions are processed by the scripts also changed. This accounts for at
least 2,700 of the ~3,600 lines of diffs in the generated code.
Most of the remaining ~900 lines of diffs are the result of bugs *fixed* by
the new scripts. The old scripts also generated code with some bugs in it.
These bugs were discovered while the new code was being written.
These changes were discussed on the mesa3d-dev mailing list back at the end
of May:

extension that was missing the GL_ part and uses the core GL type names for
vertex buffer object functions instead of the ARB names.
Also commits the resulting changes to the generated code. Some how, the
#if sequence disappeared in the 1.52 version of glapi_x86.S.

DRI drivers. A TLS enabled libGL can load a TLS or a non-TLS DRI driver,
but a TLS DRI driver requires a TLS enabled libGL.
This fixes bug #1822.

I am committing this because the current WIN32 SSE detection code crashes UnrealTournament2003.

'-DHAVE_ALIAS' to DEFINES in the config file used for building. On the
linux-dri-x86 build, this cuts 4KB from libGL.so. HAVE_ALIAS is not
currently enabled in any of the configs.

alias with the corresponding ARB functions.
GL_ARB_vertex_shader (and OpenGL 2.0's) VertexAttrib functions don't alias
with conventional vertex attributes, as GL_NV_vertex_program does.
So, the ARB and NV version of VertexAttrib need to be distinct.

(and DrawPixels). The R200, R128, and Unichrome drivers get support
in this commit. Other drivers would be easy enough to add for people
that have the cards.
The DRI (CVS) build will need to be updated to account for the new
source files.
