gdk/surface: Replace move_to_rect() with GdkPopupLayout based API Replace the gdk_surface_move_to_rect() API with a new GdkSurface method called gdk_surface_present_popup() taking a new GdkPopupLayout object describing how they should be laid out on screen. The layout properties provided are the same as the ones used with gdk_surface_move_to_rect(), except they are now set up using GdkPopupLayout. Calling gdk_surface_present_popup() will either show the popup at the position described using the popup layout object and a new unconstrained size, or reposition it accordingly. In some situations, such as when a popup is set to autohide, presenting may immediately fail, in case the grab was not granted by the display server. After a successful present, the result of the layout can be queried using the following methods: * gdk_surface_get_position() - to get the position relative to its parent * gdk_surface_get_width() - to get the current width * gdk_surface_get_height() - to get the current height * gdk_surface_get_rect_anchor() - to get the anchor point on the anchor rectangle the popup was effectively positioned against given constraints defined by the environment and the layout rules provided via GdkPopupLayout. * gdk_surface_get_surface_anchor() - the same as the one above but for the surface anchor. A new signal replaces the old "moved-to-rect" one - "popup-layout-changed". However, it is only intended to be emitted when the layout changes implicitly by the windowing system, for example if the monitor resolution changed, or the parent window moved.

* Positioning hints for aligning a surface relative to a rectangle.
*
* These hints determine how the surface should be positioned in the case that
* the surface would fall off-screen if placed in its ideal position.
*
* For example, %GDK_ANCHOR_FLIP_X will replace %GDK_GRAVITY_NORTH_WEST with
* %GDK_GRAVITY_NORTH_EAST and vice versa if the surface extends beyond the left
* or right edges of the monitor.
*
* If %GDK_ANCHOR_SLIDE_X is set, the surface can be shifted horizontally to fit
* on-screen. If %GDK_ANCHOR_RESIZE_X is set, the surface can be shrunken
* horizontally to fit.
*
* In general, when multiple flags are set, flipping should take precedence over
* sliding, which should take precedence over resizing.

gdk/wayland: Avoid relayout with the same properties When a popup is already showing, and gdk_surface_present_popup() is called, if the layout didn't change, we're not really interested in relayouting. In the future, we'll be able to get notified if position of the popup would change by some environmental changes, but until then, just don't support it.
