Connect to "grab-notify" and "grab-broken-event" and close the popup
when the grab is lost.

Patch from Jernej Simončič.

Make gimp_ui_synthesize_plus_key_event() generic and implement it with
gdk_test_simulate_key(). We can't use gtk_test_widget_send_key()
because its input window logic doesn't seem to work very well.

Test for existance of git-version.h.tmp before comparing. Otherwise
cmp will complain when building tarballs.

Fix the typo: the second x-psd should be x-psp

Don't divide by zero in gimp_session_info_class_apply_position_accuracy()
when klass->position_accuracy is 0, which happens on each exit in a normal
session.

Add missing CLEANFILES, make distcheck passes now.

Also add error margin to 'gimpsessioninfo-book.c' and update reference
files. This makes 'make distcheck' pass, and it passes more reliably.

Use of '==' as comparison operator is a bashism.

Apparently, $(abs_top_srcdir) and $(abs_top_builddir) aren't set as
shell variables any longer. Instead, use @abs_top_srcdir@ and
@abs_top_builddir@ so they get substituted at configure time.

Introduce a few pixels of error margin in sessionrc, otherwise the
tests are too fragile, widgets have a tendency to change size a bit
and window managers have a tendency to move windows a bit.

Still needs more work, should probably do the same on book positions
too...

Note:
* Passes make distcheck
* The git commit hash is shipped with tarballs
* Build handles if git-version.h is removed from a tarball

It is when we apply session info to the image window we unmaximize, so
don't apply session info to the image window when all we do is
switching tabs in single-window mode.

Simply test-xcf.c too, forgot to do that.

Update lower and upper value of adjustments *before* we set the new
value, otherwise it will be erroneously clamped sometimes.

This reverts commit 1f1f2026. It was
not proper , and correcting it reintroduces the bug :(

Add keyboard zoom focus regression test. We also need a new display
shell utility function
gimp_display_shell_push_zoom_focus_pointer_pos() for that.

Connect gimp_display_shell_hscrollbar_update to "notify::" so that the
notify freeze in gimp_display_shell_scale_update_scrollbars() works.

We don't need to call gimp_dockbook_refresh_tab_layout_lut() in
added() and removed() because we call
gimp_dockbook_update_auto_tab_style() in add() and remove().

It's too annoying to have the Paintbrush tool snap to canvas by
default.

that draws a gradient in the background of the frame. Not meant
seriously, just something to play with for everybody interested.

instead of never drawing a background. Doesn't make any difference,
but makes GimpOverlayBox a more general container. Also, the offscreen
GdkWindow doesn't need any event but GDK_EXPOSURE_MASK.

Also always return FALSE from the expose and damage event handlers.

which would have been the correct oder all the time, because these
systems are initialized in reverse order. The wrong order didn't
matter until now, but for some reason it now sometimes triggered
warnings about dialog_factories being NULL during controllers
shutdown.
