There are many non-functional whitespace and parameter name changes
included here. These were introduced upstream when converting from the
old .spec registry to the new XML registry.
There are also some new extensions added. Unfortunately there isn't a
version of the XML that matches the headers the previous versions of
the *.in files were generated from, so I can't separate out the
non-functional changes from the new extensions (other than temporarily
hacking them out of the XML). See below.
Finally, I had to hack the official glext.h. Khronos hasn't updated
the official GLES1 headers since switching to the XML registry, and
there is one critical difference: a "const void**" parameter in the
official header is "const void* const*" in the registry. I changed the
header to avoid build errors with code generated from the registry.
Dependencies on the *.in files required manually updating some
GLES_trace/ files as well:
- gltrace_api.{h,cpp} must be manually re-generated using
tools/genapi.py.
- New GL prototypes must be manually added to gltrace.proto.
- gltrace.pb.{h,cpp} must be regenerated using aprotoc (see dev.make)

Since ES3 is backwards compatible with ES2, a new wrapper isn't
necessary, and the Khronos implementation guidelines recommend
supporting both versions with the same library.

Instead of using a different function pointer table for ES 1.x and ES 2.x,
we use a single one that is the union (sort|uniq) of both tables. Two
instances of this table are initialized with pointers to GL ES 1.x and GL ES 2.x
entry-points.
When a context is created, we store its version number and when it is bound to a
thread we set the approruiate table based on the stored version.
This introduce no penalty while dispatching gl calls to the right API version.
