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).

Increase wxStaticText height in wxMSW to align its text with wxTextCtrl.
The base lines of the text in wxTextCtrl and wxStaticText which were
themselves vertically aligned didn't align, the text in the latter was one
pixel too low. This seems to be happening because we don't give enough
vertical space to the native static control by default and so, while the text
wasn't truncated, it was positioned differently than usual.
Work around this problem by allocating two extra pixels to wxStaticText
height. While the exact explanation of the problem remains mysterious, this
hack does result in correct appearance which seems to be sufficiently
important to apply it.

Make wxRefCounter non copyable.

While we could fix its copy ctor, it seems to be better to forbid copying
wxRefCounter objects at all because the semantics of doing this is not obvious

what the code using it expects it to do, as was discovered by making
