To adhere to the JavaDoc of the POITextExtractor interface which does not document a

Pictures can now be edited by calling HSLFPictureData#setData(byte[]). The byte[] should contain the image data as an image viewer might read it.
To enable this functionality, a tighter coupling between the EscherBSERecords of the slideshow and the HSLFPictureData was required. This ensures that changes in image data size are accurately recorded in the records.
In the course of coupling the records and the HSLFPictureData, various scenarios arose where a mapping of records to pictures was non-trivial. Accordingly, the HSLFSlideShowImpl#matchPicturesAndRecords(...) function was added to perform a more sophisticated matching pass. This function is heavily exercised by org.apache.poi.hslf.usermodel.TestBugs.testFile[5] and PPTX2PNG.render[2], as well as the new TestPictures#testSlideshowWithIncorrectOffsets().

We need to return EscherBlipRecord for all types in the defined range of recordId,
not UnknownEscherRecord.

The integration-tests are not executed for determining the parts of the schema
to include in the "lite" package and so we need to have a normal unit-test as well.
Add more documents which drag in some more parts from the ooxml-schema

Also improve exception reporting by including more information and not
"hiding" the actual exception-cause in a log-statement.

Field "count" seems to be optional according
to the schema, so by using only the array
Apache POI can read data validations from
workbooks that do not populate the
"count" field properly.

Profiling showed that the call to isUserDefined() took most of the time,
so we now fetch this only once for each style and remember the result and
use it in the inner loop.
The attached sample-file took aprox. 1m30s on a decent machine, now it is down
to around 2s.

Remember channel-size to no re-read it for every read-access,
but reset it if we extend the size of the file
profiling indicates Channel.size() sometimes has similar runtime
overhead as position() or read()!

introduce NameIdChunks.GetPropertyTag:
which enables evaluating property ids from properties identified by name/id in property sets (simple version of IMAPIProp::GetIDsFromNames)
AttachmentChunks.getAttachData:
use new ByteChunkDeferred instead of ByteChunk which enables delayed reading of attachments to avoid all attachments are completely read into memory when parsing which may cause OutOfMemoryErrors on e-mails with big attachments.
POIFSChunkParser:
support reading multi valued chunks (e.g. required when reading the Keywords ("categories") property)
add MAPIProperty.RECEIVED_BY_SMTP_ADDRESS
add unit tests
