Allow loading 8-bit TGA images when wxUSE_PALETTE is set to 0.
Previously the image would only be loaded when wxPalette is available. This is unneccessary and probably not wanted. Instead decode as usual but use a plain memory buffer for the palette instead of wxPalette functions and don't set the image's palette.
Always save PNG as a true colour image instead of possibly a palettised image when wxUSE_PALETTE is set to 0.
With wxUSE_PALETTE set to 0 and the user forcing to want a wxPNG_TYPE_PALETTE format the image would (partially) be marked as PNG_COLOR_TYPE_GRAY or PNG_COLOR_TYPE_GRAY_ALPHA instead and also saving would fail later on. Instead detect this specific case and save in the wxPNG_TYPE_COLOUR format.

Use wxControl instead of wxControlWithItems with wxRTTI macros.
wxControlWithItems is just a convenient combination of wxControl and
wxItemContainer mix-in and it is not useful to include it in wxRTTI classes
hierarchy. Also, using wxControlWithItems as the base class for wxChoice and
wxListBox but not for wxComboBox is inconsistent but wxControlWithItems can't
be used for the latter so resolve this by not using it at all.
Ideally we'd have a way of retrieving the list of supported interfaces (such
as wxItemContainer or wxTextEntry) via wxRTTI too.

Use wxControl as wxComboBox base class for wxRTTI in all ports.
wxComboBox only derives from wxChoice in wxMSW but not in the other ports so

Since upgrading to a newer libpng its structure members are marked as deprecated (probably as a way to discourage their direct usage). Replaced accessing them by using function calls instead.
Applied patch by troelsk which mostly makes the GIF decoder more readable by using named constants instead of magic numbers. Left out the edits that changed unsigned char to wxUint8. In addition removed unnecessary casts around wxInputStream.GetC() calls.

Add wxCompositeWindow<> and use it in wxDatePickerCtrlGeneric.
wxCompositeWindow<> is a convenient base class for composite windows, i.e.

No real changes, just remove an unneeded header dependency.
There was some commented out code in (core) valgen.cpp file using
wxDatePickerCtrl (from adv library). Also comment out the inclusion of
wx/datectrl.h header as it's not needed as long as this code remains commented
out and creates an unexpected dependency of a core library file on an adv

Only including wx/datectrl.h does not always include wx/generic/datectrl.h, for example it does not for MSW non-Universal. As a result when compiling datectlg.cpp wxDatePickerCtrlGeneric is unknown and compilation fails. Fixed by including wx/generic/datectrl.h again (regression since r66524).

This function uses the GUI toolkit information and so can't be defined in

Fix this by declaring it with WXDLLIMPEXP_CORE too. This corrects problems in
MSW DLL build.
If we need to get a string containing user-readable wxBase version too, we
should add another function (as it's not possible to virtualize this one) but
such function doesn't seem incredibly useful to have anyhow.
Tightened icon and cursor file detection heuristics.
When loading a TGA file that has an image type of uncompressed true colour it would be falsely detected as a cursor file and as an icon file if type is of uncompressed colour mapped. Lower the chance of this happening by also checking the remaining member of an ICO and CUR header which represents the number of images in the file. This member has to be non-zero (checked against all found ICO and CUR files in an XP installation).
Supports saving 24-bit and 32-bit (RGB with alpha).
Updated image unit test to verify the alpha channel of saved TGA images. Also removed a condition skipping a test which only was in place for TGA (formerly its saving handler would do nothing yet say saving was succesful).
Expanded existing image saving test to also verify alpha content of saved images.
Compare the alpha data of saved images (where applicable, currently for PNG only) to a generated alpha channel. Refactored most of ImageTestCase.CompareSavedImage into (static) function CompareImage to easily compare with a 24-bit image and then a 32-bit one.
Added some simple unit tests for verifying pixel content of loaded and saved images.
Compare the data of loaded images in different formats against a reference image (one for 8-bit images, another for 24-bit). Do the same for images saved using SaveFile. Excluded some formats because they are either lossy or don't pass the test right now.
Updated manual regarding image alpha support for BMP, PNG, and TIFF handlers.
For PNG it was mentioned only loading supports alpha, but alpha saving support has been available since r32414. Similarly there was no mention of alpha loading support for TIFF (supported since r47204) as well as BMP (since r54942).
