These properties use GdkRGBA to render the cell renderer's content.
Note that Pango attributes are used to render the foreground color,
so the alpha value is currently ignored.
This new function takes a GdkRGBA in order to set the background to
an alpha color. Keep in mind that RGBA visuals and a composited environment
are still necessary to have an alpha background displayed.
GdkRGBA is a boxed struct similar to GdkColor, with the difference
that it stores alpha information as well, and colors are stored in
[0..1] doubles, in the cairo spirit.
gdk_cairo_set_source_rgba() has been also added to allow easier handling
of this new type.
It is just too annoying to have to implement these properties in
every scrollable. Instead, we now have ::min-content-height/width
in GtkScrolledWindow.
We also add GtkScrollablePolicy to determine how to size the
scrollable content.
Since the ::changed implementation of GtkRecentManager implies a
synchronous write operation, when we receive multiple requests to emit a
::changed signal we might end up blocking.
This change coalesces multiple ::changed emission requests using the
following sequence:
• the first request will install a timeout in 250 ms, which will
emit the ::changed signal
• each further request while the timeout has not been emitted
will increase a counter
‣ if the counter reaches 250 before the timeout has been
emitted, then the RecentManager will remove the timeout
source and force a signal emission and reset the counter
This sequence should guarantee that frequent ::changed emission requests
are coalesced, and also guarantee that we don't let them dangle for too
long.

alignment/margin vfuncs adjust_size_request/allocation
Now get_height_for_width() will internally update the for_width
before passing it to the real height_for_width() vfunc, allowing
margins and extra space for alignments to be stripped, thus requesting
sufficient height for greater than natural widths (and also accounting
for margins properly). Test case adjusted in testadjustsize to ensure
proper behavior.
Create a new adjustment if there was *no* adjustment passed in, not
the other way around. Also remove unused function
gtk_tool_palette_set_adjustment().
The GtkScrollable interface provides "hadjustment" and "vadjustment"
properties that are used by GtkScrolledWindow. It replaces
the ::set_scroll_adjustment signal. The scrollable interface
also has ::min-display-width/height properties that can be
used to control the minimally visible part inside a scrolled window.
Use input-only windows for capturing input, and just draw onto
the parent window. This allows themes to make entries with rounded
corners. Patch by Boram Park.

Remove the check for GTK_TREE_MODEL_LIST_ONLY and make the view
display only the first level of the tree, ignoring all insert, remove
etc. events on the model's branches. This enables generic application
code which always produces GtkTreeStores (also for flat lists) to
display grids of these flat trees.
We lookup a widget to call a function on GtkWidget that ends up just
performing an operation directly on the GdkWindow again anyway
(beeping). There's already fallback code at the point of the call that
does exactly that anyway, so just do that all of the time.
