Changes:
+ Adapted to Python 2.1. Among other things, all uses of the
"regex" module has been repleased with "re".
+ Fixed attribute error when reading large PNG files (this bug
was introduced in maintenance code released after the 1.1.1
release)
+ Ignore non-string objects in sys.path
+ Fixed Image.transform(EXTENT) for negative xoffsets
+ Fixed loading of image plugins if PIL is installed as a package.
(The plugin loader now always looks in the directory where the
Image.py module itself is found, even if that directory isn't on
the standard search path)
+ The Png plugin has been added to the list of preloaded standard
formats
+ Fixed bitmap/text drawing in fill mode.
+ Fixed "getextrema" to work also for multiband images.
+ Added transparency support for L and P images to the PNG codec.
+ Improved support for read-only images. The "load" method now
sets the "readonly" attribute for memory-mapped images. Operations
that modifies an image in place (such as "paste" and drawing operations)
creates an in-memory copy of the image, if necessary. (before this
change, any attempt to modify a memory-mapped image resulted in a
core dump...)
+ Added special cases for lists everywhere PIL expects a sequence.
This should speed up things like "putdata" and drawing operations.
+ The Image.offset method is deprecated. Use the ImageChops.offset
function instead.
+ Changed ImageChops operators to copy palette and info dictionary
from the first image argument.
