Руслан Ижбулатов d44921a152 Enable RGBA windows on W32 
Requires Vista and newer.

* Create surfaces with cairo_win32_surface_create_with_format
* Provide an rgba visual that can be distinguished from the system visual
* Make rgba visual the best available visual
* Enable alpha-transparency for all windows that we control
* Check for appropriate cairo capabilities at configure time
  (W32 - 1.14.3 newer than 2015-04-14; others - 1.14.0)

* Check for composition support before enabling CSDs
* Re-enable transparency on WM_DWMCOMPOSITIONCHANGED
Windows that were created while composition was enabled and that were CSDed
as a result and will look ugly (thick black borders or no borders at all) once
composition is disabled.
If composition is enabled afterwards, they will return back to normal.
This happens, for example, when RDP session is opened to a desktop where a GTK
application is running. For W7/Vista windows will only re-gain transparency after
the RDP session is closed. For W8 transparency will only be gone momentarily.

Windows that were created while composition was disabled will not be CSDed
automatically and will use SSD (WM decorations), while windows that are CSDed
manually will get a thin square border.
If composition is enabled afterwards, these windows will not change.
This is most noticeable for system menus (popup menus are often generated
on the fly, system menus are created once) and some dialogues (About dialogue,
for example).

/* Cannot use TrackMouseEvent, as the stupid WM_MOUSELEAVE message
* doesn’t tell us where the mouse has gone. Thus we cannot use it to
* generate a correct GdkNotifyType. Pity, as using TrackMouseEvent
* otherwise would make it possible to reliably generate
* GDK_LEAVE_NOTIFY events, which would help get rid of those pesky
* tooltips sometimes popping up in the wrong place.
*
* Update: a combination of TrackMouseEvent, GetCursorPos and
* GetWindowPos can and is actually used to get rid of those
* pesky tooltips. It should be possible to use this for the
* whole ENTER/LEAVE NOTIFY handling but some platforms may
* not have TrackMouseEvent at all (?) --hb
