/*
* GtkCssCustomGadget is a subclass that lets widgets customize size
* requests, size allocation and drawing of gadgets. The gadget is passed
* to the callbacks as the first argument, and you can use gtk_css_gadget_get_owner()
* to obtain the widget. Note that the widgets style context is not saved,
* so if you want to query style properties or call gtk_render functions which
* take the style context as an argument, you should use
* gtk_style_context_save_to_node to make the gadget's CSS node take effect.
*
* The callbacks are
*
* GtkCssPreferredSizeFunc:
* @gadget: the #GtkCssCustomGadget
* @orientation: whether a width (ie horizontal) or height (ie vertical) is requested
* @for_size: the available size in the opposite direction, or -1
* @minimum: return location for the minimum size
* @natural: return location for the natural size
* @minimum_baseline: (nullable): return location for the baseline at minimum size
* @natural_baseline: (nullable): return location for the baseline at natural size
* @data: data provided when registering the callback
*
* The GtkCssPreferredSizeFunc is called to determine the content size in
* gtk_css_gadget_get_preferred_size(). @for_size is a content size (ie excluding
* CSS padding, border and margin) and the returned @minimum, @natural,
* @minimum_baseline, @natural_baseline should be content sizes excluding CSS
* padding, border and margin as well.
*
* Typically, GtkCssPreferredSizeFunc will query the size of sub-gadgets and
* child widgets that are placed relative to the gadget and determine its own
* needed size from the results. If the gadget has no sub-gadgets or child
* widgets that it needs to place, then a GtkCssPreferredSizeFunc is only
* needed if you want to enforce a minimum size independent of CSS min-width
* and min-height (e.g. if size-related style properties need to be supported
* for compatibility).
*
* GtkCssAllocateFunc:
* @gadget: the #GtkCssCustomGadget
* @allocation: the allocation
* @baseline: the baseline
* @out_clip: (out): return location for the content clip
* @data: data provided when registering the callback
*
* The GtkCssAllocateFunc is called to allocate the gadgets content in
* gtk_css_gadget_allocate(). @allocation and @baseline are content sizes
* (ie excluding CSS padding, border and margin).
*
* Typically, GtkCssAllocateFunc will allocate sub-gadgets and child widgets
* that are placed relative to the gadget, and merge their clips into the
* value returned as @out_clip. For clip handling in the main gadget of
* containers, gtk_container_get_children_clip() can be useful. Gadgets that
* don't have sub-gadgets of child widgets don't need a GtkCssAllocateFunc
* (although it is still required to call gtk_css_gadget_allocate() on them).
*
* Note that @out_clip *must* be set to meaningful values. If in doubt,
* just set it to the allocation.
*
* GtkCssSnapshotFunc:
* @gadget: the #GtkCssCustomGadget
* @snapshot: the snapshot to draw on
* @x: the x origin of the content area
* @y: the y origin of the content area
* @width: the width of the content area
* @height: the height of the content area
* @data: data provided when registering the callback
*
* The GtkCssSnapshotFunc is called to draw the gadgets content in
* gtk_css_gadget_draw(). It gets passed an untransformed cairo context
* and the coordinates of the area to draw the content in.
*
* Typically, GtkCssSnapshotFunc will draw sub-gadgets and child widgets
* that are placed relative to the gadget, as well as custom content
* such as icons, checkmarks, arrows or text.
*
* GtkCssSnapshotFunc:
* @gadget: the #GtkCssCustomGadget
* @snapshot: the snapshot to snapshot to
* @x: the x origin of the content area
* @y: the y origin of the content area
* @width: the width of the content area
* @height: the height of the content area
* @data: data provided when registering the callback
*
* The GtkCssSnapshotFunc is called to snapshot the gadget's content in
* gtk_css_gadget_snapshot(). It gets passed an untransformed cairo context
* and the coordinates of the area to draw the content in.
*
* Typically, GtkCssSnapshotFunc will draw sub-gadgets and child widgets
* that are placed relative to the gadget, as well as custom content
* such as icons, checkmarks, arrows or text.
