Some activities suffer from performance penalties once the number of
icons backed by SVGs exceeds 50.
Double the cache sizes.
Tested on OLPC XO-1, the weakest known system on which Sugar is used.
Steps to reproduce:
1. Long press activity icon on homeview
Expcected: Palette invokes, icon not activated
Actual: Palette invokes, icon also activated, activity launched
This was because the "activate" signal was emitted before the
palette invoker got it's signal, meaning the palette invoker couldn't
scilence the event.

In Gtk+ 3.20, you need to use the css name to select elements,
rather than the gtype name. Therefore, these must be added.
The css name must be set before the class instances are created, as
it effects the class rather than the instance. This is why it must
be places after the class definition.
With the introduction of 'activate' signal on [1], and the use of that
signal in Sugar Home, we introduced a bug, now, pressing the secondary button
starts the activity instead of open the palette.
This patch solves the issue checking the putton pressed before send the signal.

Commit a19cf9e changed the logic for handling CanvasIcon clicks. Therefore,
the visual state indicators must be updated to fit the new logic.
Test Case: Hold the mouse down on a home view icon. Move the mouse
in and out of the icon. See that the states correspond with what
happens if you release the mouse.
The industry convention for mouse driven menu options is for them
to be activated when two conditions are met:
* a button down event occurs with the pointer inside the option, and;
* a button up event occurs with the pointer inside the option.
This issue was already solved on the PaletteMenuItem,
but the EventIcon have the same problem. This change add a 'activate' event,
that control that the two conditions are meet.
The code in Sugar need use this event instead of button-release-event.
This new invoker is able to handle all the palettes on a treeview,
removing the need of one invoker per cell renderer (CellRendererInvoker).
This simplifies the code and makes it more efficient.
Also removes the logic from the CellRendererIcon, which
should only care about drawing itself. [1]
Is important to note than in Gtk3 a CellRenderer is not a GtkWidget
then can't know when the mouse is over it or have the usual events
used by other invokers, making the implementation CellRendererInvoker
very complicate.
This commit also removes the invoker of CellRendererIcon.
The ScrollingDetector logic is simplified too,
because now there are only one invoker instead of one by renderer
and the example code updated.

Detecting if the treeview is scrolling we can improve the performance of
the CellRendererIcon by avoiding unneeded calculations.
The example scrollingdetector.py shows how this can be used. The
changes are backward compatible.

pixel_size should be always used now.
Change SMALL_ICON_SIZE to cover the other sizes at settings.ini.
Adds a transformation to keep backwards compatibility for some
time. This will be removed in the future.
There are times when the entity value passed in for substitution
is of type unicode. This causes Rsvg to fail when processing the
SVG. This patch checks for unicode and converts it to utf-8.
Fixes#4621
If the icon can't be found, fall back on showing a generic icon.
Useful when activity/content bundles specify a bad icon, which is
unfortunately true for most content bundles in current existance
(because the icon field was previously unused).
When a CanvasIcon is right-clicked __button_press_event_cb and
__palette_popup_cb are called but not __button_release_event_cb. So,
ACTIVE flag is set but immediately removed by __palette_popup_cb and
PRELIGHT is set.
Now, if the user right-click it again while the palette is popped up,
__button_press_event_cb is called and it sets ACTIVE flag but
__palette_popup_cb is not called again because the palette is already
shown and that makes the icon to keep in ACTIVE state.
This patch checks if the palette is popped up when
__button_press_event_cb is called and if the palette is not popped up
the ACTIVE flag is set.

Without this patch when tapping on an EventIcon
we do get a GDK_CROSSING_UNGRAB leave event when
the Palette is raised. Because of this the Invoker
does not know how to popdown the Palette when
you tap outside or when clicking on actions in the
Palette itself.

We do not apply the clipping rectangle in do_render, we
need to call clip on the cairo_t as well. This solves the
issue in the Journal and in the Activity List View where
the icons do only appear on hovering over them.

In pygtk custom cellrenderers were done inheriting
gtk.GenericCellRenderer, and overriding the on_* methods. Now we
inherit Gtk.CellRenderer and the methods to override changed to do_* .
The destroy signal was moved to Gtk.Widget [1] so the Gtk.CellRenderer
doesn't have it anymore. Now we do the cleanup in the python
destructor method. A testcase tests/graphics/customdestroy.py shows
how is done.
tests/graphics/cellrenderericon.py tests the usage.

The icon consists of an GtkEventBox and an IconBuffer. The
GtkEventBox is a subclass of GtkBin which has its own window and
therefor is used to catch events for our IconBuffer which does
not have it's own window. The window of the EventBox is
made invisible.
The EventIcon does not emit the 'activated' signal when clicked
anymore, you can listen to 'button-release-event' to know
when the icon has been clicked. The EventIcon uses the
CursorInvoker to invoke a palette the same way as the
CanvasIcon did.
We keep the same API as with the CanvasIcon, only the 'size'
property is changed to be called 'pixel_size' in order to
make clearer which values it expects to be passed. We don't
expect a GtkIconSize to be passed here.
Another option would have been to put a SugarIcon inside a
a GtkEventBox and make the properties available through an
icon property but the API would have not been as nice and
logically it seems to make more sense to have the IconBuffer
being the base for both the SugarIcon and the SugarEventIcon.
This patch has ben developed based on the one that is
used in the shell port.

The create_palette mechanism allows to create
palettes on demand and not for each icon upfront
whether it will be needed or not.
If you hover over an EventIcon and there is no
palette already associated with the Invoker, the Invoker
will call create_palette to see if it can be created
on demand. With this patch the EventIcon will return None
here (see as well CellRendererIcon or ToggleToolButton which
are having the same default behavior).
When subclassing EventIcon the create_palette method can
be overwritten and a Palette returned (see for example
the ActivityIcon in the HomeView).
Without this patch you can see tracebacks when hovering
over the EventIcon because the Invoker tries to call
create_palette.
