1) Renamed USE_INLINE to PIL_USE_INLINE to avoid conflicts with
other headers/libraries.
2) Replace __WIN32__ and WIN32 with _WIN32
3) Don't define WIN32 when the compiler is MSVC but not on Windows
Why would you even...
4) Don't define strcasecmp if you're not even going to use it.
5) Don't include Windows.h with undefs for compilers newer than
1998 everywhere.
6) Don't surpress warnings for MSVC++ 4.0. People still using
MSVC++ 4.0 deserve it.
7) Don't include things that are already included in Windows.h
- add new FASTOCTREE quantizer with alpha support
- make ZIP compress level and type configurable
- support reading/writing PNGs with paletted alpha

This gets the putdata test case to run correctly under 2.6/2.7. It fixes an
issue where the value 0xFFFFFFFF (which is long in old Python) isn't
recognized and putdata tries to parse it as a tuple.
The original fix comes from Christoph Gohlke. It was adapted to work in
both 2.* and 3.*.
This commit also renames some functions from "fromstring" and the like to
"frombytes". I'll probably need to come back later and update any
references to "string," here or in the docs.
I also noticed that encode allocates some data for certain codecs, but
never frees them. That would be a good bug to fix. I fixed the one where it
outright stole a pointer from Python.
This commit:
* Adds Python 3 module initialization functions. I split out the main init
of each module into a static setup_module function.
* Adds a py3.h which unifies int/long in Python 3 and unicode/bytes in
Python 2. _imagingft.c unfortunately looks a little kludgy after this
because it was already using PyUnicode functions, and I had to mix and
match there manually.
With this commit, the modules all build successfully under Python 3.
What this commit does NOT do is patch all of the uses of PyArg_ParseTuple
and Py_BuildValue, which all need to be checked for proper use of bytes
and unicode codes. It also does not let selftest.py run yet, because there
are probably hundreds of issues to fix in the Python code itself.
Python 3 enables C's strict aliasing rules for the first time, which means
you need to be careful about the ways you reference pointers. Here, we're
using a char[4] as an INT32, so we cast between them using a union.
Other ports have taken advantage of the fact that Python 3 has wrappers for
the old buffer protocol, but there's a significant disadvantage: you can't
let the buffered object know when you're done with it.
Since Python 2.6 supports the new protocol, we just go ahead and move to
it.
This updates several Python type definitions and uses to bring us closer
to Python 3 compatibility. This includes:
* Replacing staticforward and statichere with static. These were a hack for
old compilers and are not supported/needed anymore.
* Using Py_TYPE() instead of ob_type; ob_type is hidden in Py3.
* Replacing getattr with getters/setters. getattr is sort-of supported in
Py3, but Py_FindMethod is not. So we just use the newer
methods/getsetters mechanisms and start using PyType_Ready everywhere.
* Use PyVarObject_HEAD_INIT for types, since types are PyVarObject.
* Use PyMODINIT_FUNC for module initialization functions.
There are some tab/space issues in this commit. I'm set for spaces; the
source is a little schizo.
