- IsThemeDialogTextureEnabled should have one parameter to match the
  prototype in the official headers.
Mike McCormack <mike at codeweavers.com>
- gcc 4.0 -Wpointer-sign fixes (Reg* functions).
Stefan Huehner <stefan at huehner.org>
- Make some function static.
- Fix -Wmissing-declarations warnings.

- Enable/disable "flat menus" based on the setting from the active
  theme.
- Have the theme INI file parsed upon theme activation and not just when
  the first theme data is requested; that way, the themed system colors
  are set correctly from the start, and not just after some theme data
  was requested.
- GetThemeBackgroundContentRect() does not use the content margins
  alone, it also falls back to the border size or sizing margins, and if
  it can't find any possible margins at all, it returns the original
  rectangle.
- Make dialog theme texture setting non-global (ie a per-window
  setting).
- Better viewport origin in DrawThemeParentBackground().
- OpenThemeData() now always sets the window theme to the handle
  returned (even if that is NULL) - previously, it could happen that
  when no theme was active or the theme data could not be opened that
  the window theme remained became then-dangling (and hence subsequent
  calls to GetWindowTheme() would return that bogus theme).
- Correct border rectangle drawing.
- Don't crash if NULL is passed as the class list to OpenThemeData().
- UXTHEME_LoadImage(): Set default image count to 1 to avoid division by
  zero in case image count property is not given. Properly support 0
  state IDs.
- Every window needs to receive WM_THEMECHANGED (esp. controls), so also
  send it to child windows.
- Changed the default transparent color in case none was explicitly
  specified from the upper left pixel color to magenta. Empirically
  gives better results.
- Write WCHAR strings to registry with correct size.
- Opening some theme class data now also increases the reference count
  of the theme file, so as long as theme class data is still opened
  somewhere, the theme file won't get freed. Otherwise, it could happen
  that invalid class data was used, which could lead to problems.
