finally, apps that prefer dark theme variant (gtk-application-prefer-dark-theme
in GtkSettings) should also have dark window decorations

frames: apply modified hack from Mutter/Metacity

2019-09-12T13:14:51+00:00

- this will be needed for proper window decoration color updates on theme change
  when theme variants fixes are applied

- realize/unrealize functions are dropped instead of map/unmap ones, because
  we didn't change these during GTK+3 porting

- MetaFrames now has GtkWindow as parent instead of GtkInvisible, otherwise
  the hack doesn't work (revert part of 96c7256d638b8c76c8abf786ba307e82a595dd67)

frames: use style_updated instead of style_set

2019-09-12T13:13:45+00:00

guess it was overlooked when porting to GTK+3

Fixed moving windows to edges to work with CSD clients.

window: Update allowed action hints

2019-09-12T13:06:56+00:00

When changing window state, we want to change the allowed action hints
so that other applications, mainly the taskbar, can disable menu entries
that do not make much visual sense. For example, unmaximizing
a minimized window: even though this operation is possible, it causes
user confusion as there is no visibility until the user unminimizes it.

Fix use of RBGA visual in frame.c when compositing is not in use

2019-09-10T15:17:36+00:00

Use the window's visual in all cases, fix problems with drivers forcing use of blit rather than pageflip mode when comppositing is not used or window is unredirected

boxes: Actually check for rectangle containment

2019-07-02T14:30:27+00:00

Fixes condition duplicated:

          /* If a contains b, just remove b */
          if (meta_rectangle_contains_rect (a, b))
            {
              delete_me = other;
            }
          /* If b contains a, just remove a */
          else if (meta_rectangle_contains_rect (a, b))
            {
              delete_me = compare;
            }
