Thomas Weidenmueller <wine-patches@reactsoft.com>
- It should be allowed to pass NULL handles in the phpage array of the
  PROPSHEETHEADER structure to PropertySheet(), just ignore them.
Aric Stewart <aric@codeweavers.com>
- Fix for dreamweaver site definition dialog. Need to initialize the
  rect for a tab control to an empty rect if it is not visible.
Alexandre Julliard <julliard@winehq.org>
- Don't prefix the functions DllCanUnloadNow, DllGetClassObject and
  Dll(Un)RegisterServer with the dll name so that the compiler can check
  the prototypes.
- Fixed regression in DPA_Search.
Yuri Kozlov <kozlov.y@gmail.com>
- Set default size for toolbar bitmap if not specified.
Mike McCormack <mike@codeweavers.com>
- Fix gcc 4.0 warnings.
Vitaly Lipatov <lav@etersoft.ru>
- Use STATEIMAGEINDEX / INDEXTOSTATEIMAGEMASK instead of bit
  operations.
Steven Edwards <steven_ed4153@yahoo.com>
- Correct RegCreateKeyEx[A/W] prototype to match the PSDK.
Frank Richter <frank.richter@gmail.com>
- Only draw a themed border when edit control has WS_EX_CLIENTEDGE
  style.
- Merge subclass stubs and subclass proc. Having the stub set the window
  proc to the subclass proc was not a good idea since that breaks
  subclasses of themed standard controls (e.g. what Delphi does a lot).
- Determining the superclass for a window subclassed for theming doesn't
  work - e.g. Delphi buttons have the classname "TButton" for which no
  superclass will be found. Instead, use initial subclass window procs
  that have the subclass hardcoded and store it for the "real" subclass
  window proc.
- Add theming for toolbar control.
- Improved trackbar theming.
- Add initial theming support for trackbars.
- Add theming for treeview control.
- Add theming support for dialogs (to support tab page background).
- Add theming for listbox (and combo listbox) controls.
- Add theming for combo boxes.
- Subclass edit control to draw themed border.
- Added some generic code to allow subclassing (for the purpose of
  theming) of standard controls.
- Fix warnings in 64bit.
- Add hottracking support for the header control.
- Since OpenThemeData() should return 0 in case theming is disabled
  globally or for the application we don't need to check that when
  calling OpenThemeData().
- Remove unneeded theming check.
- Add theming for the monthcal control.
- Instead of adding the border via WM_NCPAINT and WM_NCCALCSIZE, do what
  native does: just clear WS_EX_STATICEDGE when themed and reduce the
  area the actual bar is painted in to the progress bar theme part
  content rect.
- Add theming for the progress control.
- Split up the drawing code into a set of smaller functions and also
  moved some common computations into helper functions. All that to
  facilitate the implementation of the forthcoming theming support.
- Add theming for the rebar control.
- Add theming for status bar control.
- Fix text color for "button" style tabs when theming is enabled.
- Add theming support for the tab control.
- Forward WM_DESTROY to superclass in edit & listbox theming.
- Add WM_CTLCOLORSTATIC handler to dialog theming subclass so static
  text can appear transparent (for e.g. tab pages which commonly have a
  "fancy" background).
