+ * The following GtkScrolledWindow widgets have hardcoded minimum sizes,
+ * because there seems to be (in GTK+ versions before 3.22) no way to
+ * set the natural size of GtkScrolledWindow and its GtkViewport.
+ *
+ * I tried:
+ *
+ * - Setting size requests of the sizes of child widgets plus
+ * scrollbars (commit 2205669)
+ * - Putting GtkScrolledWindow widgets in stacks with non-scrolled
+ * versions of children, to allocate more area for the
+ * GtkScrolledWindow widgets to fill (commits 922cdef and 90686fa)
+ * - Setting policies to disable scrollbars upon GtkScrolledWindow
+ * instantiation, then enabling scrollbars on the GtkScrolledWindow
+ * "size-allocate" signal (commits c534c7e and 42ca783)
+ *
+ * Attempts to match the size of a GtkScrolledWindow's GtkViewport to
+ * its child's size don't allow the GtkScrolledWindow and GtkViewport to
+ * shrink when necessary to fit within the window. Therefore, such
+ * methods are equivalent to simply not using GtkScrolledWindow at all.
+ * And there appears to be no easy way to calculate the available size
+ * (the size of the GtkWindow minus all of the surrounding widgets) to
+ * manually manage a GtkViewport's size.
+ *
+ * GtkScrolledWindow or GtkViewport ignores the child's preferred
+ * (minimum and natural) sizes and apparently just sets a hardcoded size
+ * of about 64x64 px. I considered subclassing GtkScrolledWindow or
+ * GtkViewport, but I'm not sure where the hardcoded size is set.
+ *
+ * The functions gtk_scrolled_window_set_propagate_natural_width() and
+ * gtk_scrolled_window_set_propagate_natural_height() were introduced in
+ * GTK+ 3.22 and probably do what I want. However, I want to maintain
+ * compatibility with at least GTK+ 3.12 or 3.14.
