Update 2.8.10.1 to 2.8.12.0
2.8.12:
-------
All:

- Fixed a bug in UNC path testing.
- Improved command line parser usage help.
- Fixed race condition bugs in wxCondition.
- Added wxT_2() for forward compatibility with wxWidgets 3. Use it in
  initialization of wxCmdLineEntryDesc struct elements and (very few) other
  places where wxT() is required currently but won't be allowed in v3.
- Fixed crash on exit caused by deleting old logger in wxLogChain dtor.

All (GUI):

- wxRTC: fixed style selection resetting after editing a style.
- wxRTC: can now edit line spacing in .1 increments from 1 to 2.
- wxRTC: fixed wrong line spacing and space after paragraph calculations.
- wxRTC: GetStyleMergedWithBase now detects loops.
- wxRTC: wxRichTextCtrl::ApplyStyle now applies a paragraph style at the
  cursor without needing a selection, and setting the default style now
  avoids duplicating character attributes in subsequently typed text when
  they exist in the paragraph style.
- wxRTC: fixed IsPositionVisible to scroll a position into view correctly.
- wxRTC: fixed a problem with paste resetting the content paragraph style.
- wxRTC: style list box now copes with names duplicated across style types.
  Also fixed wxRichTextStyleDefinition::GetStyleMergeWithBase similarly.
- wxRTC: fixed very poor performance for XML loading on wxGTK.
- Fixed error in generic tree control CalculatePositions.
- Added wxFD_FILE_MUST_EXIST to wxFileSelector function.
- Added wxDataViewCtrl Get/SetValueByRow functions for forward compatibility
  with 2.9.
- Right-clicking is now supported in any kind of wxAuiToolBar button.
- Fixed a bug in wxAcceleratorEntry::IsOk.
- wxGraphicsContext::DrawBitmap: x and y coordinates no longer affected by
  stretch factor.
- Fixed an assert in wxGrid on wxEVT_MOUSE_CAPTURE_LOST.
- Fixed bug in generic wxTreeCtrl where SelectItem toggles the selection if
  the item is already in the desired state.
- Fixed bug in wxSizer::Replace(size_t, wxSizerItem *) whereby SetContainingSizer
  is not called.
- Fixed compilation with libpng 1.5 and above.
- Removed ugly black (simple) border around wxHTML help window.

wxMSW:

- wxOwnerDrawnComboBox and wxComboCtrl with wxCB_READONLY window style now
  have more native-like focus indicator rendering.
- Fixed wxOwnerDrawnComboBox keyboard handling: drop-down is no longer
  displayed when arrow key is pressed (without Alt).
- In some rare cases wxOwnerDrawnComboBox drop-down animation could display
  as garbage. This has now been greatly reduced (mcben).
- Fixed OLE date conversion bug.
- Added check for double window handle creation.
- Fixed WIN64 crash in wxStyledTextCtrl.
- Fixed Watcom compilation when omitting threads.
- Fixed wxFileName::IsFileReadable on Windows 98.
- Fixed bug whereby clicking anywhere inside wxListBox generates
  wxEVT_COMMAND_LISTBOX_SELECTED event. You need to set wxUSE_LISTBOX_SELECTION_FIX
  to 1 in include/wx/msw/listbox.h to enable this binary-incompatible fix.

wxGTK:

- Fix for --disable-radiobtn compilation.
- Fixed a bug on GTK+ only whereby wxGrid scrolls back to the previous edit position
  when another cell is edited.
- Fix for missing menubar problem under some window managers where menu bar height is
  reported as 0 when the menu hasn't fully realized yet. Now updates the height during
  idle time if it is 0, otherwise no menu is shown.
- Improved list control and tree control selection text theme compatibility by adding
  wxSYS_COLOUR_LISTBOXHIGHLIGHTTEXT colour index.
- wxComboCtrl and wxOwnerDrawnComboBox had wrong background colours under some
  themes (Marcin Wojdyr).
- Added thread-safe fixes to socket code.

wxUniv:

- Fixed assertion in tree control sample due to colour index not being supported.

2.8.11:

*** INCOMPATIBLE CHANGES: ***

   Due to an oversight, a bug fix in wxMSW resulted in an incompatible change in
   wxTreeCtrl behaviour: its EVT_TREE_ITEM_ACTIVATED handler now must skip the
   event being processed to allow the item to be toggled by double clicking on it.
   I.e. you need to ensure there is an "event.Skip()" in your item activation
   handler if you do wish to allow the item to be toggled.

All:

- Fixed crashes due to invalid input in PNG and TIFF image loaders (Tielei Wang).
- Fix compilation of wxWidgets headers with recent Sun CC (Brian Cameron).
  NB: If your code uses _T() macro you must either replace it with wxT() to
      use Sun CC or define wxNEEDS__T before including wx headers and avoid
      including many standard headers (again, only with this compiler).
- Added several functions forward compatible with wxWidgets 3.0 (troelsk):
  wxDC::SetDeviceClippingRegion(), wxShowEvent::IsShown(),
  wxIconizeEvent::IsIconized(), wxFileName::StripExtension(),
  wxXmlNode::GetAttribute[s](), wxXmlNode::AddAttribute().
- wxDateTime timezone functions now dynamic (no caching).

All (GUI):

- Add wxBU_EXACTFIT support to wxToggleButton XRC handler (Ronny Krueger).
- wxRTC: fixed AltGr+key input and numeric keypad Delete on Windows.
- wxRTC: added background colour setting to font dialog.
- wxRTC: added wxRICHTEXT_HANDLER_USE_CSS flag for HTML handler to use CSS
  where possible.
- wxRTC: corrected centring and right-justification spacing.
- wxRTC: corrected some problems with SelectAll. Caret is now set to end.
- Paper size conversion from dimensions to id now uses definition ordering
  in order to use common types where there are duplications, fixing problems
  where invalid sizes caused incorrect second invocation of page setup
  dialog.
- Corrected writing direction for Farsi.
- Added wxBORDER_THEME to XRC.
- Speeded up wxTreeCtrl by caching text size (botg).
- Fix building with using system libpng 1.4 (Volker Grabsch).
- Fixed generic wxDatePickerCtrl keyboard navigation.
- Added EVT_WIZARD_PAGE_SHOWN event for wxWizard.

wxMSW:

- Fixed crash when copying Unicode URLs to the clipboard (Tim Kosse).
- Fixed generation of wxEVT_CHAR_HOOK events.
- Implement wxFileName::SetTimes() for directories (Steve Lamerton).
- Correct wxTopLevelWindow::SetShape() for windows with menu bar (Peter Friis).
- Backported speed-up of Vaclav Slavik's high quality print preview speed-up.
  You now need to set wxUSE_HIGH_QUALITY_PREVIEW_IN_WXMSW in
  src/common/prntbase.cpp and wxUSE_ENH_METAFILE_FROM_DC in
  include/wx/msw/enhmeta.h.
- Worked around child window and caret positioning bug (in Windows) when using
  wxBORDER_THEME in a container window.
- Suppressed spurious character event for decimal key in numeric keypad.
- Prevented wxCheckListBox from corrupting menu items.

wxGTK:

- Don't access a possibly destroyed timer object from GTK callback (Tim Kosse).

wxMac:

- Fixed a problem with wxListCtrl whereby event processing would change
  the event object identifier, and thereby affect subsequent processing,
  and defeat custom event propagation of commands from current focus window.
- Fixed a problem with wxFontDialog on Mac OS 10.6.
