Document which wxRegion methods can and can't be used when the region itself
is invalid.
Apply the minor changes to wxGTK (Xor() didn't do the right thing, Offset()
didn't assert) and wxOSX (Offset() crashed) to make their behaviour consistent
with wxMSW.
Add a (trivial, so far, but to be extended later) wxRegion unit test checking
that the methods do indeed behave as documented.

This is a facade for wxDataViewCtrl allowing to easily work with multi-column
trees, possibly with an optional checkbox in the first column. Its API is very
similar to wxTreeListCtrl and it provides a simple migration path from the
latter.
Add the class itself, documentation for it and minimal unit tests.

Having wxBITMAP_TYPE_TIFF and wxBITMAP_TYPE_TIFF_RESOURCE is more consistent with already using the complete short name of an image format elsewhere (e.g. wxBITMAP_TYPE_JPEG, not wxBTMAP_TYPE_JPG, and wxTIFFHandler as opposed to wxTIFHandler). Renamed all existing occurrences and kept the old enum values for backwards compatibility.
Also renamed occurrences of wxBITMAP_TYPE_RESOURCE to the already existing wxBITMAP_TYPE_BMP_RESOURCE.

wxDataViewCtrl::GetSelection() now always returns invalid item if more than
a single item is selected in a multi-selection control.
Also add HasSelection() and GetSelectedItemsCount() to allow checking if any
items are selected.
Updated the documentation, all ports and added a test for all these functions.

CPPUNIT_ASSERT_EQUAL() gives more informative error messages in case of
failure which is important when running tests unattended on build slaves.

IsEmpty() didn't exist in all ports (notably not wxMSW) and its meaning was
unclear anyhow, so remove it even from the ports where it did exist and add
clear Is{List,Text}Empty() replacements instead.

The recently added BMP images in tests/image/ were not being copied. Added them to test.bkl and regenerated makefiles.

Added option wxIMAGE_OPTION_TIFF_PHOTOMETRIC for reading and writing TIFF images. This is mostly for being able to distinguish between PHOTOMETRIC_MINISBLACK (chocolate flavour) and PHOTOMETRIC_MINISWHITE (vanilla) as currently the flavour used was fixed. It applies to greyscale as well as black and white images. Added unit tests to verify the written photometric value.
Also see #13194.

When saving with a samples per pixel value of 1 the TIFF handler still treated the image as RGB, resulting in corrupted images. Handle the greyscale case and added a unit test for it.

When setting only wxIMAGE_OPTION_TIFF_BITSPERSAMPLE to 1 the used samples per pixel (wxIMAGE_OPTION_TIFF_SAMPLESPERPIXEL) would still be set to 3. This is invalid and confuses libtiff, resulting in a crash ("possible heap corruption" during _TIFFfree using WinXP+MSVC8). Set the used samples per pixel to 1 explicitly in cases where only bits per sample is set to 1. Added a unit test to check for this problem (and verify the bits per sample from the saved image is indeed 1).

Libtiff attempts to seek past the end of a stream and the behaviour for this can vary per stream implementation. Fixed failure to seek by filling the gap between the end of stream and new seek position with zeroes. Enabled a unit test which so far was disabled due to wxMemoryOutputStream failing to save a TIFF because of the seeking problem.
Also closes#4089.

The BMP decoder did not handle images that are not stored upside down but straight up (in which case the height is negative). Also with RLE4 or RLE8 compressed images the 'end of scanline' RLE marker was not handled correctly. Fixed the issues and added a unit test for them.

First, enable execution of the Lines() wxTextCtrl unit test case under wxOSX
as it passes since the fix in the previous commit.
Do add a test for GetNumberOfLines() that currently doesn't work in the same
way under all platforms -- but with this test we at least can be sure how does
it work exactly where.
Also mention the current discrepancy in this function behaviour in the
documentation.
See #12366.
Fix Lines() wxTextCtrl unit test to pass under wxGTK too.

Negated long options were not recognized in wxCmdLineParser::Parse(), do check
for them now.
Also extend the unit test to check for negated options.
Closes#13335.

The internally stored date value was getting out of sync with the real date in
the control itself when SetValue() was called with a date out of the currently
set range. This resulted in an assert failure and other unpleasantness later.
Fix the bug and add a unit test checking for it (and also with some other
basic wxDatePickerCtrl checks).

No real changes, just refactor the code to allow using CPPUNIT_ASSERT_EQUAL
with wxDateTime in other tests in the future.
