Added option to TIFF handler for specifying the photometric interpretation.
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.
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.
Changed TIFF handler's monochrome conversion to look at the green channel instead of red.
It's common when reducing a coloured image to greyscale or black and white to give the green channel more significance. Since we're only looking at a single channel use the green one instead of red.
Fixed crash when saving as a monochrome TIFF image with incomplete options set.
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).
The loading/saving options that are specific for TIFF were in the form of wxIMAGE_OPTION_<name> while all other non-generic options use the form wxIMAGE_OPTION_<imagetype>_<name>. Renamed the TIFF options to the form wxIMAGE_OPTION_TIFF_<name> and kept the old names for backwards compatibility.
moved description of wxIMAGE_OPTION_GIF_COMMENT from wxImage::GetOptionInt documentation to wxImage::GetOption because the value of the GIF option is a string, not int.
When reducing an RGB image to black and white any non-black pixel was treated as white resulting in mostly white images. Set the threshold to 127 instead to improve the looks of saved monochrome TIFF images.
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.
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.

Avoid creating rect with negative size while clipping to DC size.
Also, don't convert result of wxDC::GetSize() to device coords, it's already device coords.

Rename wxWebNavigationError to wxWebViewNavigationError and wxWebNavigationEvent to wxWebViewEvent. This makes the names more consistent with other parts of wxWidgets.

Fix return value of wxMBConvUTF8::ToWChar() when not using MAP_INVALID_UTF8_NOT.
wxMBConvUTF8::ToWChar() was off by 1 when the input length was explicitly
specified, the extra NUL should only be added in the implicit length case.
This bug didn't occur for the default wxMBConvUTF8 object as it simply
forwarded to the base class wxMBConvStrictUTF8 implementation but it happened
when MAP_INVALID_UTF8_TO_OCTAL or MAP_INVALID_UTF8_TO_PUA was used.

Fix bitmap position attribute name in XRC handler.
Bitmap position attribute was called "bitmapposition" in the documentation and
in the code that generated an error message for a wrong value in it but was
inexplicably called "direction" in the code that really looked it up.
This seems to be just a straight typo from the original r61065. Surprising as
it is that it wasn't noticed before, do correct it now.

No changes, just remove gratuitous inefficiency from generic wxDVC.
Don't return wxDataViewMainWindow::m_selection array by value, returning a
const reference to it is enough and avoids completely unnecessary memory
allocations and copying of potentially large amounts of data.
Also make wxDataViewMainWindow::GetSelections() const.

Use separate strings for stock labels with and without mnemonics.
Obtaining the string without mnemonics by simply removing "&" characters from
the string containing mnemonics doesn't work for some languages, notably
Chinese where the convention is to use "Chinese Text (&M)" for the labels with
"M" being the ASCII mnemonic and just "Chinese Text" and not "Chinese Text (M)"
should be used if wxSTOCK_WITH_MNEMONIC flag is not specified.
Fix the fundamental problem by using separate strings for the two cases.
Translations still need to be updated to really correct the labels appearance.
Since r68621 dataview.cpp didn't compile anymore (at least with wxOSX-Carbon). Fixed by explicitly using wxDataViewItem's void * constructor in a few cases.
The code to update m_selection was too aggressive in the virtual list
case, when it simply cleared it, and broken for single-item selection in
the general case.
Fixed to recompute selection properly.

Make the wxDataViewItem(void*) constructor explicit.
Not having this as an implicit one made it possible to create
wxDataViewItem from any pointer without realizing it, leading to hard to
debug crashes later.
Added NSApplicationDelegate's openFiles for wxOSX-Cocoa.
openFiles (available since OS X 10.3) replaces using the openFile method. It allows for more convenient handling of multiple drops and knowing in advance how much files/folders are dropped instead of openFile with which you only get to respond to a single file/folder drop at a time. By default openFiles calls the newly added MacOpenFiles which calls MacOpenFile multiple times, so ordinarily the behaviour is backwards compatible (both on wxOSX Cocoa and Carbon).
The openFile instance method has been removed because it doesn't seem to be called anymore: neither when dropping a single file on the application in the dock or Finder nor when passed as a command-line argument.

Don't manually centre dialogs created with default position in wxMSW.
We always centered the dialogs on the main display which was wrong if the

them at all and let Windows position them, there is no reason to change the
default behaviour.

Fix compilation with g++ 4.7 (prerelease).
The workaround for a bug in g++ 3.5 breaks compilation with 4.7 which
implements two-phase lookup correctly, so disable this workaround for 4.7 and
later. We could probably even only enable it for 3.x but this doesn't really
matter as previous 4.x releases don't have problems with this anyhow.
