Dumps the widget path into a string representation. It tries to match the CSS
style as closely as possible (Note that there might be paths that cannot be
represented in CSS).
The main use of this code is for debugging purposes, so that you can
g_print() the path or dump it in a gdb session.
The metacity theme format allows to use colors from the current
GTK+ theme in window decorations. Since GTK+ now gained support
for dark theme variants, window managers using that theme format
(metacity, mutter, compiz via gtk-window-decorator) should be able
to use colors from the correct variant; so in case a variant is
requested, export it in the _GTK_THEME_VARIANT property on
toplevel windows.

gtk_entry_set_placeholder_text() makes the entry display the given text
when it is empty and unfocused. Based on previous patch by Alberto
Garcia.

GDK_NATIVE_WINDOWS was a way to keep some old apps running that did weird
things in gtk2. We should not have to carry this forwards in gtk 3.x.
We do however keep a g_warning() call reminding people of this fact to
ease debugging when they try to port their applications.

Now that a single shared object can contain multiple backends we also
need to provide a simple way for third party code to verify that the
copy of GDK they are linking to supports their backend.
The simplest way to verify is an m4 macro, GTK_CHECK_BACKEND(), shipped
with the gtk+ m4 macros.
The usage is pretty basic:
GTK_CHECK_BACKEND([x11], [gtk_has_x11=yes], [gtk_has_x11=no])
AM_CONDITIONAL(BUILD_X11_CODE, test "x$gtk_has_x11" = "xno")

At the same time, change the library sonames for -3.0 to just -3.
This is necessary since the 2.99 releases installed libraries like
libgtk-3.0.so.0.9903.0, and we want to prevent the library version
number from jumping back. So 3.0 will have libgtk-3.so.0.0.0.
The previous function gdk_drag_get_protocol_for_display() took native
window handles, so it had to be changed. Because it didn't do what it
was named to do (it didn't return a protocol even though it was named
get_protocol) and because it doesn't operate on the display anymore but
on the actual window, it's now called gdk_window_get_drag_protocol().
... and all APIs making use of it.
That code like it hasn't been touched in years, Google codesearch
didn't find any users and most importantly it's a horrendous API, so
let's just make it die instead of having to port it over to
non-GdkNativeWindow usage, which would be required for multi-backend
GDK.
