glTexImage3D that caused me so many problems during the re-development
of the API scripts reared its ugly head again. This has been fixed by
tracking the parameter string for each entry-point individually.
This has the annoying side-effect that the names of the parameters in
all aliases of a function must be the same or gl_apitemp.py will
generate bad code. :( The changes in
src/mesa/glapi/{gl_API.xml,glapitable.h} and src/glx/x11/* are caused
by fixing the parameter names in various function aliases that didn't
match.

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:

generates the correct script name in the generated output.

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.

no error detection, slow, may not be 100% correct but a good start

missing enum information for GL_EXT_cull_vertex and
GL_SGIS_texture_color_mask. Added GL_SUN_mesh_array. Corrected the
spelling of the "length" parameter to GetActiveUniformARB.

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.

broken, but it will be fixed "shortly." This is pretty much the same
as the patch I sent to the dri-devel list on 22-Jun-2004.

The internal driver interface was also changed to use
BlendEquationSeparate instead of BlendEquation.

Adjust makefiles to create depends and not store it in CVS
Remove dependency on kernel pci_ids.h
|

Added non-static entrypoints and the name string for
GL_SUN_multi_draw_arrays (identical to GL_EXT_multi_draw_arrays).
Made add_newer_entrypoints (in src/mesa/main/context.c) table driven.
This reduced the size of context.o by about 3KB.
