Add widget_set_size in the initiate time to allow smoke get the
correct surface later. Or it will report segment fault error because
of the null surface.
Also add resize_handler to not allow resizing just like flower.

As some distros are shipping linkers, that do not resolve symbols from
implicitly linked libraries, check and link libpng explicitly.

Do not build toytoolkit applications that use GL, if Cairo-egl is not
available. These applications (which happen to be also the full GL
clients) do not work at all without Cairo-egl, and fail at runtime with
"unable to acquire window surface".

When window_attach_surface() calls window_get_resize_dx_dy(),
window->resize_edges is cleared. However if there is already a pending
surface to be attached, the resize won't be done until the following
call to window_attach_surface(). In this next call, since resize_edges
is now zero, the top-left corner of the window will be unchanged. If
the user is resizing from the top or left border, this causes the
resize to happen in the wrong direction.
This patch changes window_attach_surface() to call
window_get_resize_dx_dy() only if an attach will actually happen.

This reverts commit fc6ccb868f.
We still need root permissions for drmDrop/SetMaster. Without
integration with ConsoleKit or systemd we also don't have access
to /dev/dri/cardX in the case where we open a new VT.
The code which sends the button events was checking whether there is a
focus widget with a button handler but then always sending the button
event to the grab widget. If the grab widget is different from the
focus widget at this point then it will check the wrong widget for a
button handler and potentially crash. It is also possible for there to
be no grab widget here in the following situation:
1. Press and hold down the left mouse button
2. Press and hold down the right mouse button
3. Release the left mouse button
4. Release the right mouse button
In this case the grab will be released at step 3 because the code only
keeps track of the grab for one button. Then it will try to send the
release event for the right mouse button to a NULL widget so it will
crash.

Modify popup_grab_focus() to deal with a NULL surface.

When a menu self-destructs, free also the widget and struct menu.
As menus are self-destructing, it does not make sense to store the
window pointer, since we cannot clear it automatically. Therefore,
rename window_create_menu() to window_show_menu() that does not return
the window pointer. It also calls window_schedule_redraw() internally.
Fixes Valgrind reported memory leaks.
The alternative would be to explicitly destroy the menu in application's
menu callback.

Input devices may hold a pointer to the widget being destroyed. Reset
such pointers in widget_destroy().
This fixes a use-after-free in window_destroy(), if an application
destroys its widgets before the window.

Fix a memory leak reported by Valgrind, by destroying the window
decorations widget, if it exists.
All widget pointers returned from toytoolkit to the application should
be destroyed by the application explicitly.

When we destroy a surface, we damage the surface below so that the area
exposed by the disappearing surface will be repainted. However, if that
surface also is destroyed, the damage information is lost and we fail to
repaint that area.
This commit introduces weston_surface_flush_damage(), which flushes the
surface damage the the surface below when a surface is destroyed. When
multiple surfaces are destroyed at the same time, the damage now accumulates
and sinks down through the surface stack as it should.
gbm_bo_create_from_egl_image() should catch this based on the
GBM_BO_USE_CURSOR_64X64 flag. It currently doesn't so we end up with
a cursor buffer with invalid stride.
The decorations were not responding, could not move or resize the
dialog, and it painted with a black shade.
When the dialog is created, schedule a resize instead of a repaint. The
resize will initialise the widget tree, and let everything draw and work
as it should.
