We now have proper checks for gdk_screen_is_composited() and a proper
implementation for gdk_screen_get_rgba_visual() for Windows, so we
can remove the comments in this file stating that they aren't
available for Windows.
Catch an error that indicates the file looks like a template,
and then try again, this time with the template parsing API
of GtkBuilder. This is a little iffy, since we need to create
a 'fake' type and instance to pass in, but it works ok in
simple tests.
Add the class and parent class name to the error message.
gtk-builder-tool will parse the error message and use the
class names for trying again to parse the file as a template.
I was getting really weird values for scale for the blank cursor used
when hiding the cursor in a GtkEntry when typing, this was caused
by gdk_wayland_device_update_window_cursor sending random values
when the returned buffer was NULL.
We fix this by just not sending any buffer or scale updates in this
case.
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).

Without this change, out-of-tree distcheck doesn't get very far.
Similarly, allow *.vcxproj, *.props to be in either the builddir or
the srcdir.
Finally, since I'm touching these lines anyway, eliminate some
useless uses of cat: "cat x | sed 's/foo/bar/' > y" is
equivalent to "sed 's/foo/bar/' < x > y".

Add a convenience function that is like gtk_builder_get_object()
but stashes away a GError if a lookup fails. To make the error
message informative, the function takes a line/column pair.
Doing things this way is necessary because the custom_tag_end,
custom_finished, and parser_finished vfuncs don't take a
GError parameter, despite being called from a place where
we can report a GError back.
GdkKeymap already has support for _get_num_lock_state() and
_get_caps_lock_state(). Adding _get_scroll_lock_state() would be good
for completness and some backends (Windows?) could take advantage of
this.
We want to clear the style property cache whenever things change in the
tree, not as we previously did only when those changes actually lead to
a different CSS style.
