Log Message:
Update wxGTK to 2.6.3. Feel responsible for now.

Important changes:
- Fixed crash when loading message catalogs in Unicode build.
- Spurious error message from wxLaunchDefaultBrowser fixed.
- Compilation fixes for (more strict) g++ 4.1
- Speed improvements to wxRegEx when matching is done in a loop such as
  during a search and replace.
- Fix regerror and regfree name conficts when built-in regex and system regex
  are both used in the same program.
- wxCondition::WaitTimeout() now returns correct value when timeout occurs.
- Bug in wxLogStream::DoLogString in Unicode builds fixed.
- Fixed Unicode builds using SunPro compiler by defining__WCHAR_TYPE__.
- wxFileName now also looks for TMPDIR on Unix.
- Fixed occasional wxThread cleanup crash.
- Fixed build error in list.h with VC++ 2005.
- wxImage::Copy() forgot the alpha channel.
- Fixed wxSocketBase::InterruptWait on wxBase.

- Fixed abort() on loading invalid PNG image
- Added space after list item number in wxHTML.
- wxCalendarCtrl drawing, positioning and hit-testing fixes.
- More checking of image validity before loading into wxImage.
- Added double-buffering to wxVListBox and fixed a scrolling issue.
- More than one filter allowed in in wxDocTemplate filter.
- Fixed infinite loop in tab traversal code with wxUSE_STL==1

- Fixed problem with choice editor in wxGrid whereby the editor
  lost focus when the combobox menu was shown.
- Fixed problem trying to print from a preview, whereby wrong printer
  class was used.
- Worked around pango crashes in strncmp on Solaris 10.
- Polygon and line drawing speeded up if there is no scaling.
- Fixed problems with CJK input method (reverted)
- Fixed wxNotebook::HitTest when the leftmost visible tab is not the
  actual first tab (has arrows for scrolling and is scrolled).
- Send wxSetCursorEvent
- Fix RequestMore for idle events.
- Implement user dashes for PS and GNOME printing.
- Correct update region code. Don't always invalidate the
  whole window upon resize. Reenable support for the
  wxNO_FULL_REPAINT_ON_RESIZE flag. Also disable refreshing
  custom controls when focusing in and out.
- Change wxMimeTypesManager code to ignore /etc/mailcap and
  to just read the MIME-types. Modifiying the MIME-types is
  not allowed under GNOME anyways, so make it a no-op.
- Speed up reading MIME database.
- wxClipboard fixes (thanks to Timothée Lecomte).

Additionally the build system has been libtoolified to simplify
maintainance of the shared libraries in the PLIST. Patches against
the bakefile ruleset are included for reference.

The Unicode build is not enabled, since the interface changes to
drastical.
