The TexSubImage commands do not have the "NULL image" flag that was
introduced with glTexImage3D. However, there is a CARD32 pad element
where that flag would be. Removing the img_null_flag causes the flag
to be removed from the protocol. This changes the protocol and breaks
everything.
In order to prevent needing to hand-code all of the TexSubImage
functions, a new attribute was added to the param element. This new
attribute, called "padding," is a boolean flag that selects whether or
not the parameter is a real parameter (default / false) or is protocol
padding (true) that does not appear in the function's parameter list.
This change resulted in a number of changes to other Python scripts.
In almost all cases parameters with the is_padding flag set should not
be emitted.
This patch only changes the the XML, the DTD, and the generator
scripts. It does NOT include the resulting changes to the generated
code. Generated code in the X server is also changed by the script /
XML changes in this patch.

boolean attribute, which defaults to true, determines whether or not a
static dispatch function is available in libGL for applications to link
against.
Ideally, any new functions that are not part of the ABI should not have
directly accessable dispatch functions. This forces applications to use
glXGetProcAddress to access these functions. By doing this we can
gracefully remove functions from libGL without breaking the linkage of
applications.
Note that the static dispatch functions are still generated. However, they
are given names like gl_dispatch_stub_820 and are marked with the "hidden"
linker attribute.
All extension functions added since the previous Mesa release (6.5) have
been marked as 'static_dispatch="false"'.

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.
